Which method returns the next integer less than or equal to a given number?

In the C Programming Language, the ceil function returns the smallest integer that is greater than or equal to x (ie: rounds up the nearest integer).

Syntax

The syntax for the ceil function in the C Language is:

`double ceil(double x);`

Parameters or Arguments

xThe value to round up to the nearest integer.

Returns

The ceil function returns the smallest integer that is greater than or equal to x.

In the C Language, the required header for the ceil function is:

`#include `

Applies To

In the C Language, the ceil function can be used in the following versions:

• ANSI/ISO 9899-1990

ceil Example

```/* Example using ceil by TechOnTheNet.com */

#include
#include

int main(int argc, const char * argv[])
{
/* Define temporary variables */
double value;
double result;

/* Assign the value we will find the ceil of */
value = 1.6;

/* Calculate the ceil of value */
result = ceil(value);

/* Display the result of the calculation */
printf("The ceil of %f is %f\n", value, result);

return 0;
}```

When compiled and run, this application will output:

`The ceil of 1.600000 is 2.000000`

Similar Functions

Other C functions that are similar to the ceil function:

• floor function

The INT function allows you to return the nearest integer less than or equal to a specified value.

Syntax of INT

The syntax of the INT function is simply:

``INT ( value);``

where:

• value is the number you are assessing

Example

An example is

``INT (11.6);``

This will return 11.

An example of a negative number is

``INT (-11.6);``

This will return -12.

INT can be used in both TI’s and Rules.

It works identically to the same function in Excel.

The Math.ceil method is used to return the smallest integer greater than or equal to a given number. The ceil() is always used as Math.ceil() since it is a static method of Math.

Syntax:

`Math.ceil(value)`

Parameters: This method accepts single parameters as mentioned above and described below:

• Value: It is the value that is to be tested for Math.ceil.

Return Value: The Math.ceil() method returns the smallest integer greater than or equal to the given number.

ceil() — Find Integer >=Argument

Format

``````#include
double ceil(double x);``````

ANSI

Yes

Description

The `ceil()` function computes the smallest integer that is greater than or equal to x.

Return Value

The `ceil()` function returns the integer as a double value.

Example

This example sets y to the smallest integer greater than 1.05, and then to the smallest integer greater than -1.05. The results are 2.0 and -1.0, respectively.

``````#include
#include

int main(void)
{
double y, z;

y = ceil(1.05);       /* y = 2.0 */
z = ceil(-1.05);      /* z = -1.0 */

printf("y = %.2f ; z = %.2f\n", y, z);
}
/***************** Output should be similar to: ***********************

y = 2.00 ; z = -1.00
**********************************************************************/``````

The `Math.ceil()` function always rounds up and returns the smaller integer greater than or equal to a given number.

``````Math.ceil(x)
``````

`x`

A number.

The smallest integer greater than or equal to `x`. It's the same value as `-Math.floor(-x)`.

Because `ceil()` is a static method of `Math`, you always use it as `Math.ceil()`, rather than as a method of a `Math` object you created (`Math` is not a constructor).

In this tutorial, we will learn how to get the largest integer that can be less than or equal to a number in JavaScript.

To get the largest integer less than or equal to a number, we use the Math.floor() method in JavaScript. It is used to round off a number supplied as a parameter to its closest integer towards the downward direction of rounding, i.e., towards the less significant value.

Following are two ways in which we find the largest integer that can be less than or equal to a number in JavaScript.

Using Math.floor() Method

The method Math.floor() returns the greatest one integer that is less than or equal to a specified value. Because floor() is a static Math function, you should always use it as Math.floor() instead of using than as a method of a Math object you constructed (Math is not a constructor).

It returns the integer that is greatest but less than or equal to the supplied number. Math is a placeholder object that includes mathematical constants and functions, one of which is floor().

Syntax

```Math.floor(value);
```

A decimal or integer value is supplied to the Math.floor() method as a parameter to compute the integer less than or equal to that value.

Example

The Math.floor() function helps to evaluate the nearest integer less than or equal to a number. In this example, we see that some variables are passed to the floor() function, and it returns a value.

```

Get the largest integer less than or equal to a number using
Math.floor() method

```

The variable value1 takes an input of a decimal number and returns its nearest rounded-down integer. The variable value2 takes the input of a negative decimal integer. The value3 variable takes the input of a number nearby zero, which gives a zero value to the console.

A decimal number is passed to the Math.floor() function, and the result gets stored in the value4 variable.

Using the external mathematical library method

In this method, we will use an external modern mathematical library known as math.js. This library is used for complex computational facilities.

Math.js includes a versatile expression parser with symbolic computing support, a huge range of constants and built-in functions, and an integrated solution for working with various data types such as integers, fractions, complex numbers, fractions, and big numbers, fractions, units, and matrices.

It is a large math library for JavaScript. It is effective and simple to use. It is compatible with JavaScript's built-in Math library. It can run on any JavaScript engine. It is readily expandable. Math.js is an open-source technology.

Syntax

```math.floor(value);
```

The value is supplied as a parameter to the math.floor() function.

Example

The math.floor() method may be used to get the nearest integer that is less than or equal to a given value. We can see in this example that several variables are supplied to the floor() method, which returns a result. The script tag is used to incorporate the math.js library.

In this tutorial, we have learned about the two techniques used to find the largest integer that can be less than or equal to a number in JavaScript. The first technique is to use the built-in Math library of JavaScript and its floor() function. The second technique is to use a mathematical library that can be applied to all the mathematical functions in the code.
