+ | ======pow(base, exponent) ====== | ||
+ | |||
+ | ====Description ==== | ||
+ | |||
+ | Calculates the value of a number raised to a power. Pow() can be used to raise a number to a fractional power. This is useful for generating exponential mapping of values or curves. | ||
+ | |||
+ | ====Parameters ==== | ||
+ | |||
+ | base: the number (''float'') | ||
+ | |||
+ | exponent: the power to which the base is raised (''float'') | ||
+ | |||
+ | ====Returns ==== | ||
+ | |||
+ | The result of the exponentiation (''double'') | ||
+ | |||
+ | |||
+ | ====Example ==== | ||
+ | See the [[http://arduino.cc/playground/Main/Fscale|fscale]] function in the code library. | ||
+ | |||
+ | ====See also ==== | ||
