Float literal details

[cbaggers]

Floats can also be defined using exponential notation, using the e or E to separate the base from the exponent. The exponent is always base-10.

In GLSL 4.00 and above, double-precision floats are available. By default, all floating-point literals are of type float. To create a double-precision float, use the lf or LF suffixes. This will force it to the double type.```
