The modf function can extract the integer and decimal parts of a floating-point number. The fmod function returns the remainder of the division of two floating-point numbers. Their function prototypes are as follows:

Double _ _ cdecl modf (double _ X _ Magi double * _ Y); double _ _ cdecl fmod (double _ X _ Magi double _ Y)

The functions of these two functions look simple, but why is there a special function in the C language library for calculation? Before using these two functions, let's first look at a simple floating-point number-related example.

Int main () {int i; float jacked 1.0; for (iTuno; I
