Numbers

WCL has fixed-width signed and unsigned integers, plus two float widths. A bare integer literal defaults to i64; a suffix pins the exact type. Underscores may group digits for readability.

Literals

a = 42          // i64 (default)
b = 200u8       // unsigned 8-bit
c = 9_000i64    // underscores are ignored
d = 3.14f64     // float
e = -120i8      // signed
f = 0xFFu32     // hex
g = 0b1010_1100u8   // binary
h = 0o755u16    // octal

Types

Numeric promotion

Arithmetic and comparison widen mixed numeric operands to a common type, so cross-width and integer/float mixing work without explicit casts.

a = 1 + 2.0        // i64 widened to f64 → 3.0
b = 1u32 == 1i64   // true
c = 3.0 * 2u8      // 6.0
