 Syntax for Reid is very much inspired by rust, and examples of the language can
 be found in the [examples](../examples/)-folder.

+#### `pub fn clamp(min: f32, max: f32, value: f32) -> f32`
 
 Returns `value` as clamped between `min` and `max`. Equivalent to `max(min(value, max), min)`

+#### `pub fn abs(value: f32) -> f32`
 
 Returns the absolute value of `value`.
