Remap

Linearly maps a value from source range [srcMin, srcMax] onto destination range [dstMin, dstMax]. Optional clamping prevents the output from exceeding the destination bounds.

Sockets

value (in): Float. The value to remap.
srcMin, srcMax (in): Floats. Source range bounds (override the parameters).
dstMin, dstMax (in): Floats. Destination range bounds (override the parameters).
value (out): Float. The remapped result.

Parameters

Src Min: Low end of the source range. Default: 0.
Src Max: High end of the source range. Default: 1.
Dst Min: Low end of the destination range. Default: 0.
Dst Max: High end of the destination range. Default: 1.
Clamp: When on, the output is clamped to [dstMin, dstMax]. When off, out-of-range inputs extrapolate linearly.

How It Works

t = (value - srcMin) / (srcMax - srcMin)
out = dstMin + t * (dstMax - dstMin)

If srcMin == srcMax the source range is degenerate and the output falls back to dstMin. Negative ranges (dstMax < dstMin) are supported — the mapping simply inverts.
