In PHP I have decimal numbers that may or may not have trailing zeros.
For example
1
1.1
43.87
How do I make sure that all these numbers have exactly two decimal places like this:
1.00
1.10
43.87
927
$twoDecNum = sprintf('%0.2f', round($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. Save this answer.
Rounding a decimal number to two decimal places is the same as rounding it to the hundredths place, which is the second place to the right of the decimal point. For example, 2.83620364 can be round to two decimal places as 2.84, and 0.7035 can be round to two decimal places as 0.70.
PHP | number_format() Function. The number_format() function is an inbuilt function in PHP which is used to format a number with grouped thousands. It returns the formatted number on success otherwise it gives E_WARNING on failure.
The %. 2f syntax tells Java to return your variable (value) with 2 decimal places (. 2) in decimal representation of a floating-point number (f) from the start of the format specifier (%).
You should use number_format():
number_format(1.1, 2);
