When two integers are divided, because the number after the decimal point is truncated, so that the result of the operation is an integer, so if you want to get the result of the operation is the expected floating-point number, then the two integers must be one or all cast as floating-point numbers.For example:(float) A/b cast one of the integers to a floating-point number, and then divide by another integerA/(float) b(float) A/(float) b//convert two
PHP has two decimal places, and php has two decimal places.
Recently, I am making statistics on this part. There are many data sources related to numbers,
Three functions are used to retain the last N digits after decimal places. Next, we will briefly introduce the three functions:
1. number_format

This article mainly introduces jquery's number after determining two decimal places and automatically deleting two decimal places. If you need a friend, you can refer to jquery's number after determining two decimal places and automatically deleting two decimal places.
Basically, enter 12.235689741
It will be convert
Php uses the number_format function to extract decimal places for analysis. number_format decimal places
This example describes how php uses the number_format function to intercept decimals. We will share this with you for your reference. The details are as follows:
We all know that the number_format () function in php can group numbers by thousands, but it will round the number. Is there a way for it to
