norm()

Category: Math

Subcategory: Calculation

Complexity: Intermediate

Description

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

map()
lerp()

Example

Code:

Copy

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