Name

norm()

Description

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

Numbers outside the range are not clamped to 0 and 1, because out-of-range values are often intentional and useful. (See the second example above.)

Examples

float value = -10;
float n = norm(value, 0, 100);
println(n);  // Prints "-0.1"

float value = 20;
float n = norm(value, 0, 50);
println(n);  // Prints "0.4"

Syntax

norm(value, start, stop)

Parameters

value(float)the incoming value to be converted
start(float)lower bound of the value's current range
stop(float)upper bound of the value's current range

Return

float

map()
lerp()
