centerex()

Removes jitter around zero and applies exponential curve to number.

Applies an advanced centering transformation to the input value based on a minimum threshold, maximum range, and exponential center scaling.

If the absolute value of the input is smaller than `min`, it returns 0.

If the absolute value is greater than or equal to `max`, it returns ±1.

Otherwise, it applies a scaled transformation between the thresholds.

Syntax

centerex(value, min, max, center)

Parameter	Type	Description
value	Number	The numeric value to transform.
min	Number	The lower threshold below which the value becomes zero.
max	Number	The upper threshold at which the value reaches ±1.
center	Number	The exponential scaling factor that adjusts the response curve.

centerex(2, 3, 10, 5);  // returns 0 (below min)

centerex(5, 3, 10, 5);  // returns 0.28571429 (transformed value)

centerex(-5, 3, 10, 5); // returns -0.28571429 (transformed value)

centerex(12, 3, 10, 5); // returns 1 (above max)

centerex(-12, 3, 10, 5); // returns -1 (above max)
