Summary
Function: float fSclFix( float from_min, float from_max, float to_min, float to_max, float from );Rescales a value from one range to another range.
The value is also clamped between the 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 fSclFix(float from_min, float from_max, float to_min, float to_max, float from) {
from = to_min + ((to_max-to_min) * ((from_min-from) / (from_min-from_max)));
if(to_min < to_max) {
if(from < to_min) from = to_min; else if(from > to_max) from = to_max;
} else {
if(from < to_max) from = to_max; else if(from > to_min) from = to_min;
}
return from;

Examples
float value = fSclFix(0.0, 1.0, -5, 15, 0.6); // value == 7
