static double Exponent::MathTools::CParameter::doubleToDouble	(	const double	min,
		const double	max,
		const double	value
	)			[static]

Convert a double to a differently mapped double range

Parameters:

	min	The minimum value (negatives are acceptable)
	max	The maximum value (negatives are acceptable)
	value	The value to convert to the remapped value. must be in range 0 - 1

Return values:

double

The remapped value

static long Exponent::MathTools::CParameter::doubleToLong	(	const long	min,
		const long	max,
		const double	value
	)			[static]
