math modf() function

C++ Math modf() This function is used to divide a number into integral and fractional part. For example : 2.16 = 2 + 16 Syntax Suppose a number is 'x' and 'ptr' is the pointer to an integral part. float modf(float x, float* ptr); double modf(double x, double* ptr); long double modf(long double x,...
