The method of converting binary to floating-point number by php

In php, to convert a binary to a floating-point number, you need to first convert the binary to a decimal number.

Implementation method:

1. Use the bindec () function to convert binary numbers into decimal numbers.

The bindec ($binary_string) function converts the binary number $binary_string to a decimal number.

2. Use the type conversion function floatval () or settype () to convert decimal numbers to floating-point numbers.

Floatval () function

The floatval () function is a function that specifically converts other types to floating-point types, and it gets the floating-point value of a variable.

Echo "

The data types of decimal numbers are: "; var_dump ($num); $float= floatval ($num); echo" modified type: "; var_dump ($float)

Settype () function

Echo "

The original data type is: "; var_dump ($num); settype ($num," float "); echo" modified type: "; var_dump ($num)

At this point, the study of "how php converts binary to floating-point numbers" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
