def setup():
    value = 20
    n = py5.norm(value, 0, 50)
    py5.println(n)  # Prints "0.4"

    py5.println(n)  # Prints "-0.1"

Description

Normalizes a number from another range into a value between 0 and 1. Identical to remap(value, low, high, 0, 1).

Numbers outside of the range are not clamped to 0 and 1, because out-of-range values are often intentional and useful. (See the second example.) If that isn’t what you want, try pairing this function with constrain().

Syntax

norm(value: Union[float, npt.NDArray], start: Union[float, npt.NDArray], stop: Union[float, npt.NDArray]) -> Union[float, npt.NDArray]

Parameters

  • start: Union[float, npt.NDArray] - lower bound of the value’s current range

  • stop: Union[float, npt.NDArray] - upper bound of the value’s current range

  • value: Union[float, npt.NDArray] - the incoming value to be converted
