- Basic Information
- pow() calculates number raised to power in C++
- Function is part of <cmath> header and std namespace
- Accepts base and exponent parameters
- Returns double type result
- Prototypes
- Standard prototype works with double types
- Float prototype handles float types
- Long double prototype works with long double types
- Integer exponent prototype available for double-to-integer operations
- Special Cases
- Base=0 returns 0.0
- Exponent=0 returns 1
- Non-zero base and exponent result in non-zero result
- Integer Usage
- Converts integer arguments to double automatically
- Integer exponent with floating-point base possible
- Integer arithmetic generally faster than floating-point
- Large integer results may cause overflow
