float
| Property | Value |
|---|---|
| Alias of | float64 |
| Size | 8 bytes (64 bits) |
| Format | IEEE 754 binary64 (double precision) |
| Decimal precision | ~15–16 digits |
| Hardware support | Native on all supported targets |
float is a built-in, compiler-provided alias for float64 — the default floating-point type in Rux:
type float = float64; // compiler intrinsic alias
Because the alias is transparent, float and float64 are the same type and fully interchangeable. Use float in everyday code; spell out float64 when the exact width is the point (serialisation, FFI signatures).
Literals
When a floating-point literal is written without an annotation or suffix, Rux infers float64:
let a = 1.0; // float64
let b = 3.14; // float64
let c: float = 0.5; // same type, by alias
Arithmetic, Comparison, and Conversion
float behaves identically to float64 in every respect — operators, NaN and Inf rules, rounding, and conversion. See the float64 page for the full reference.
