Functions
double	FpCurveUp (double fpVal, double mEffect)
	Takes a floating-point value (double) between 0.0 and 1.0 and returns a new value within the same range, with output values skewed or "leaning" upward (toward 1.0) in a curve with a controlled shape.
double	FpCurveDn (double fpVal, double mEffect)
	Takes a floating-point value (double) between 0.0 and 1.0 and returns a new value within the same range, with output values skewed or "leaning" downward (toward 0.0) in a curve with a controlled shape.
double	FpCurveUpRs (double fpVal, double mEffect)
	Takes a floating-point value (double) between 0.0 and 1.0 and returns a new value within the same range, with output values skewed or "leaning" upward (toward 1.0) in a curve with a controlled shape that is more extreme closer to 0.0 and tapers off closer to 1.0, resulting in a curve that bends into a special shape.
double	FpCurveDnRs (double fpVal, double mEffect)
	Takes a floating-point value (double) between 0.0 and 1.0 and returns a new value within the same range, with output values skewed or "leaning" downward (toward 0.0) in a curve with a controlled shape that is more extreme closer to 0.0 and tapers off closer to 1.0, resulting in a curve that bends into a special shape.
double	FpCurve1D_u_in (double fpVal, double mEffect, double cntPnt)
	Takes a floating-point value (double) between 0.0 and 1.0 and returns a new value within the same range, with output values skewed or "leaning" inward toward a given center point value in a curve with a controlled shape.
double	FpCurve1D_u_out (double fpVal, double mEffect, double cntPnt)
	Takes a floating-point value (double) between 0.0 and 1.0 and returns a new value within the same range, with output values skewed or "leaning" outward away from a given center point value in a curve with a controlled shape. The value will curve toward either 1.0 or 0.0, depending on which one would NOT mean crossing the center point.

	Takes a floating-point value (double) between -1.0 and +1.0 and returns a new value within the same range, with output values skewed or "leaning" outward away from 0.0. The value will curve toward either -1.0 or +1.0, depending on which one would NOT mean crossing 0.0.
float	FpUcurve_f (const float inpVal, const float hard)
	Takes a (float) of any value and outputs a value from -1.f to +1.f, along a curve, so that as the input value gets farther from 0.0f it slows down and never quite gets to +1.f or -1.f.

	Takes a (float) of any value and outputs a value from -1.f to +1.f, along a curve, so that as the input value gets farther from 0.0f it slows down and never quite gets to +1.f or -1.f.

◆ FpCurve1D_s_out()

double FpCurve1D_s_out	(	double	fpVal,
		double	mEffect )

Takes a floating-point value (double) between -1.0 and +1.0 and returns a new value within the same range, with output values skewed or "leaning" outward away from 0.0. The value will curve toward either -1.0 or +1.0, depending on which one would NOT mean crossing 0.0.

Parameters

[in]	fpVal	Initial floating-Point value (double) to be altered. May range from -1.0 to +1.0.
[in]	mEffect	How extreme the effect is (the shape of the curve). A value of 0.0 is no curve or effect at all, while a value of 1.0 is for maximum effect (very extreme).

Returns: The new, altered value.
