It uses the Processing version when called with five numeric arguments, and otherwise falls back to Python’s built-in. Note: the same approach is used for `filter()`.\n\nBy contrast, py5 avoids the conflict by renaming the function to  [`remap()`](https://py5coding.org/reference/sketch_remap.html) instead.\n","author":{"url":"https://github.com/SableRaf","@type":"Person","name":"SableRaf"},"datePublished":"2026-04-24T13:06:16.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/131/libprocessing/issues/131"}
