Constants

As great as it is to know what happens under the hood, it would be nice to have convenient ways to...

• check what is the difference in precision for Pi as an f32 vs an f64
• see what the minimum or maximum value for a given type is, like i128 or u128.
• represent infinity or negative infinity or NaN

That's where constants come in.

fun fact: in the source code, NAN is represented as 0.0_f32 / 0.0_f32, INFINITY as 1.0_f32 / 0.0_f32, and NEG_INFINITY as -1.0_f32 / 0.0_f32. Dividing by zero appears to have its uses :)

fn main() {
//TODO: Add examples
}

Check a given type's documentation to see what kind of constants they have available. For example, std::i128 and std::f32
