math fabs() function

C++ Math fabs() It computes the absolute value of a given number. Suppose a number is 'x': fabs(x) = |x|; Syntax float fabs(float x); double fabs(double x); int fabs(int x); Parameter x: The value whose absolute value is to be determined. Return value It returns the absolute value of x. Example 1 Let's see the simple example...

math trunc() function

C++ Math trunc() The function rounds off the given value towards zero and returns the nearest integral value whose magnitude is not greater than the given value. For example: trunc(3.8) = 3; Syntax Suppose a number is 'x'. Syntax would be : return_type trunc(data_type x); Note: return_type can be float,double or long double. Parameter x:...

math fmod() function

C++ Math fmod() The function finds the floating point remainder of numerator/denominator and rounded towards zero. Formula of fmod: fmod= numerator - t*denominator where 't' is the truncated value of numerator/denominator. Syntax Consider a numerator 'n' and denominator 'd'. Syntax would be: double fmod(double n,double d); Parameter n:The value of numerator. d:The value of denominator Return value It...
