=====pow=====
Syntax:
#include
double pow( double base, double exp );
The pow() function returns base raised to the expth power. There's a domain
error if base is zero and exp is less than or equal to zero. There's also a
domain error if base is negative and exp is not an integer. There's a range
error if an overflow occurs.
C++ also provides the following overloaded forms:
#include
float pow( float base, float exp ); // same as powf() in C99
long double pow( long double base, long double exp ); // same as powl() in C99
C++ also provides overloaded versions of pow() that perform integer exponentiation:
#include
float pow( float base, int exp );
double pow( double base, int exp );
long double pow( long double base, int exp );
