float value = 20;
float n = norm(value, 0, 50);
println(n);  // prints "0.4"
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.
norm(value, low, high)
value float: The incoming value to be converted
low float: Lower bound of the value's current range
high float: Upper bound of the value's current range
Returns float
