This article will explain in detail how to use float floating-point data types in PHP. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Description: decimal, floating point (also known as floating point float, double precision double or real real)

Decimals in php can be expressed in two forms: ordinary decimals or scientific counting.

Code example:

/ / 1var_dump ($num); / / 1$ num = 9.999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999

Note: never believe that floating-point results are accurate to the last digit, and never compare whether two floating-point numbers are equal. If you really want higher precision, you should use any precision mathematical function or gmp function.
