mapRange

See source on Github 

The mapRange function remaps a number from one range to another. It takes a value in a given range (inMin to inMax) and maps it to a corresponding value in a target range (outMin to outMax). This function also optionally clamps the input value to ensure it stays within the input range before mapping, preventing values outside the range.

  • @param value - The number to be mapped from the input range to the output range.
  • @param inMin - The lower bound of the input range.
  • @param inMax - The upper bound of the input range.
  • @param outMin - The lower bound of the output range.
  • @param outMax - The upper bound of the output range.
  • @param clamp - If true, the input value will be clamped to stay within the inMin to inMax range. If false or omitted, the value will be mapped regardless of whether it falls outside the input range.
  • @returns The value mapped from the input range to the output range. If clamp is true, the returned value will always correspond to a value between outMin and outMax.

Example

// Map a value from the range [0, 100] to [0, 1]
mapRange(50, 0, 100, 0, 1) // 0.5
// Map a value from the range [0, 100] to [0, 1000] with clamping
mapRange(150, 0, 100, 0, 1000, true) // 1000 (clamped)
// Map a value from [10, 20] to [100, 200]
mapRange(15, 10, 20, 100, 200) // 150
