double exp(double x);
double log(double x);
double log10(double x);
double pow(double x,double y ); The exp() function returns the value of e (the base of natural logarithms) raised to the power of x. The log() function returns the natural logarithm of x.
The log10() function returns the base-10 logarithm of x.
The pow() function returns the value of x raised to the power of y.
The log() function can return the following errors: - EDOM
- The argument x is negative.
- ERANGE
- The argument x is zero. The log of zero is not defined.
The pow() function can return the following error:
- EDOM
- The argument x is negative and y is not an integral value. This would result in a complex number.
