Interpolation/Rescale/Float

Summary

Function: float fScl( float from_min, float from_max, float to_min, float to_max, float from );

Rescales a value from one range to another range.
Returns a float

• float	from_min	–	Minimum of range From
• float	from_max	–	Maximum of range From
• float	to_min	–	Minimum of range To
• float	to_max	–	Maximum of range To
• float	from	–	Value in range From

Specification

float fScl(float from_min, float from_max, float to_min, float to_max, float from) {
    return to_min + ((to_max-to_min) * ((from_min-from) / (from_min-from_max)));
}
