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 = 20;
    float n = norm(value, 0, 50);
    println(n);  // Prints "0.4"
    
  • float value = -10;
    float n = norm(value, 0, 100);
    println(n);  // Prints "-0.1"
    

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
