Hướng dẫn remove decimal php
I am currently echoing a number like this: Show
The problem is that the number normally has a decimal place such as I need to display the full number but without the decimal point or any of the numbers behind it. I know that you can round to the full number in PHP but I don't ever want it to round up. If the only way to do this is with rounding, I need it to always round down... asked Jul 31, 2014 at 14:50

2 In this article, I show you how to get Php 2 decimal places without rounding off the actual number. This is important when you are working on some math calculation script and your results are varying because of the decimal values. This is a very common scenario to handle decimal places in numeric figures. Nội dung chính Suppose you have below value – 30.67798 And you want the get value up to two decimal without rounding off using PHP and below is the expected output – 30.67 Example -1 $amount = 30. 67798; $rounded_amount = round($amount, 2); Output – 30.67 Here I used the round method to round the decimal value up to two places. The first parameter is the actual value and the second parameter is the precision. The precision parameter is optional and the default value is Zero. $rounded_amount = round($amount, 0); Output –
Example -2 PHP 2 decimal places without roundingLet’s understand the round() method in PHP. It round the decimal point value. Note –
Example 1 Output 1 3
"); echo(floor(2.40)); ?> Output 0 2 Round to 2 decimal places PHP Now let’s take one more example to round to two decimal places in PHP. "; return round($number,$afterDot) ; } ?> Output – num1 = 275, num2 = 0, num3= 100 2.75 Example 3- Have a look at the below expression so that you will never forget how to round to two decimal places in PHP. "); echo(round(40.5666) . " Output – 10 41 302 -10 60 Note – The round method expects only the number value if you pass any string the syntax error has occurred.

How can I get 2 decimal places in PHP?$twoDecNum = sprintf('%0.2f', round($number, 2)); The rounding correctly rounds the number and the sprintf forces it to 2 decimal places if it happens to to be only 1 decimal place after rounding. Show activity on this post. This will give you 2 number after decimal. How do I limit decimal places in PHP?Parameter Values Specifies a constant to specify the rounding mode: PHP_ROUND_HALF_UP - Default. Rounds number up to precision decimal, when it is half way there. Rounds 1.5 to 2 and -1.5 to -2. What is precision PHP?Precision is defined as the number of significant digits, and scale is the number of digits behind the decimal point. This means that a number like “1.23E-1000” would require a scale of 1002 but a precision of 3. Decimal uses precision, where bcmath uses scale. How do you round decimals?Put simply, if the last digit is less than 5, round the previous digit down. However, if it's 5 or more than you should round the previous digit up. So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up. And if it is followed by 0, 1, 2, 3, 4 round the number down. |
