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
<lsl>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)));
} // Released into public domain. By Nexii Malthus.</lsl>
Examples
<lsl>float value = fScl(0.0, 1.0, -5, 15, 0.6); // value == 7</lsl>
