Struct FloatValue 

pub struct FloatValue { /* private fields */ }

Wrapper around an f32 value that is internally casted to an isize, in order to provide hash-ability (to avoid numerical instability).

Implementations

impl FloatValue

pub const fn const_new(value: isize) -> Self

Same as FloatValue::new(), but only accepts whole numbers. Uses isize arithmetic to avoid floating-point in const context.

pub const fn const_new_fractional(pre_comma: isize, post_comma: isize) -> Self

Creates a FloatValue from a fractional number in const context.

This uses integer arithmetic to represent fractional values like 1.5, 0.83, etc. in const context without relying on f32 operations.

The function automatically detects the number of decimal places in post_comma and supports up to 3 decimal places. If more digits are provided, only the first 3 are used (truncation, not rounding).

Arguments

• pre_comma - The integer part (e.g., 1 for 1.5)
• post_comma - The fractional part as digits (e.g., 5 for 0.5, 52 for 0.52, 523 for 0.523)

Examples

// 1.5 = const_new_fractional(1, 5)
// 1.52 = const_new_fractional(1, 52)
// 1.523 = const_new_fractional(1, 523)
// 0.83 = const_new_fractional(0, 83)
// 1.17 = const_new_fractional(1, 17)
// 2.123456 -> 2.123 (truncated to 3 decimal places)

pub fn new(value: f32) -> Self

pub fn get(&self) -> f32

pub const fn number(&self) -> isize

Returns the raw encoded isize (the f32 value scaled by FP_PRECISION_MULTIPLIER). Exposed so external callers can round-trip the value through the compact-cache encoding without re-multiplying through f32.

pub fn interpolate(&self, other: &Self, t: f32) -> Self
