public static float Pow(float f, float p)

Parameters

f

float
Base of the exponentiation operation.

p

float
Exponent of the exponentiation operation.

Returns

Type

Description

floatResult of the exponentiation operation.

Remarks

The behaviour of exponentiation varies greatly depending on the sign and range of the exponent 
p
:
  • For real numbers in the range [1, ∞], the result of exponentiation is equal to the result of multiplying 
    f
    by itself 
    p
    times.
  • For fractional numbers in the range (0, 1), the result of exponentiation is equal to the result of computing the n-th root of 
    f
    , with n being 1/
    p
    .
  • For the value 0, you will get the value 1.
  • For real numbears in the range [-∞, 0), the result of exponentiation is equal to the result of diving 1 by the result of raising 
    f
    to the absolute (non-signed) value of 
    p
    .
