Numbers
=======
{{#include ../links.md}}
Integer numbers follow C-style format with support for decimal, binary ('`0b`'), octal ('`0o`') and hex ('`0x`') notations.
The default system integer type (also aliased to `INT`) is `i64`. It can be turned into `i32` via the [`only_i32`] feature.
Floating-point numbers are also supported if not disabled with [`no_float`]. The default system floating-point type is `i64`
(also aliased to `FLOAT`). It can be turned into `f32` via the [`f32_float`] feature.
'`_`' separators can be added freely and are ignored within a number - except at the very beginning or right after
a decimal point ('`.`').
| Format | Type |
| --------------------- | ---------------- |
| `123_345`, `-42` | `INT` in decimal |
| `0o07_76` | `INT` in octal |
| `0xabcd_ef` | `INT` in hex |
| `0b0101_1001` | `INT` in binary |
| `123_456.789`, `-42.` | `FLOAT` |
