Function Documentation

bool Divides	(	double	smallerNumber,
		double	largerNumber
	)

Uses fmod to determine if smallerNumber divides the largerNumber. We expect smallerNumber/largerNumber <= 1 and therefore fmod(largerNumber,smallerNumber) should be close to zero or close to smallerNumber.

Parameters:

smallerNumber	the smaller
largerNumber	the larger

Definition at line 78 of file MathsCustomFunctions.cpp.

double SmallPow	(	double	x,
		unsigned	exponent
	)

Replacement "pow" function.

Parameters:

x	number to be raised to a small power
exponent	small integer exponent

Returns:

x^exponent a.k.a x**exponent.
