fabs()Prototype: double fabs(double number);Header File: math.h (C) or cmath (C++) Explanation: This function returns the absolute value of a number. It will not truncate the decimal like abs() will, so it is better for certain calculations. Example: //Example outputs absolute value of -12.3 with fabs and abs #include <cmath> #include <iostream> int main() { cout<<"Abs(-12.3)="<<abs(-12.3)<<endl; cout<<"Fabs(-12.3)="<<fabs(-12.3); }Other Functions |
