Functions

deficit_of

The non-negative shortfall of cur below max.

f64_to_i32_saturating_ceil

Rounds an f64 upward and saturates it to i32.

f64_to_i32_saturating_round

Rounds an f64 to the nearest integer and saturates it to i32.

f64_to_i32_saturating_trunc

Truncates an f64 and saturates it to i32.

f64_to_i64_saturating_floor

Rounds an f64 downward and saturates it to i64.

f64_to_i64_saturating_round

Rounds an f64 to the nearest integer and saturates it to i64.

f64_to_i64_saturating_trunc

Truncates an f64 and saturates it to i64.

f64_to_u8_saturating_trunc

Truncates an f64 and saturates it to u8.

f64_to_u32_saturating_ceil

Rounds an f64 upward and saturates it to u32.

f64_to_u32_saturating_round

Rounds an f64 to the nearest integer and saturates it to u32.

f64_to_u32_saturating_trunc

Truncates an f64 and saturates it to u32.

f64_to_u64_saturating_ceil

Rounds an f64 upward and saturates it to u64.

f64_to_u64_saturating_floor

Rounds an f64 downward and saturates it to u64.

f64_to_u64_saturating_round

Rounds an f64 to the nearest integer and saturates it to u64.

f64_to_u64_saturating_trunc

Truncates an f64 and saturates it to u64.

f64_to_usize_saturating_round

Rounds an f64 to the nearest integer and saturates it to usize.

f64_to_usize_saturating_trunc

Truncates an f64 and saturates it to usize.

float_eq

Compares two floats for equality within EPSILON tolerance.

float_ne

Inverse of float_eq.

i32_to_u8_saturating

Saturates an i32 to the range representable by u8.

i32_to_u32_nonnegative

Converts a nonnegative i32 to u32, clamping negative values to zero.

i64_to_f64

Converts an i64 to f64 with the same rounding as Rust’s native cast.

interpolate_sorted

Interpolates x over points sorted ascending by their first coordinate.

pct_of

cur as a percentage of max, returning 0.0 when max <= 0.

round_to_decimals

Rounds an f64 to the requested number of decimal places.

safe_div

Returns 0.0 on division by zero instead of panicking.

true_mod

True modulo: result has the sign of the divisor (unlike Rust’s %); 0.0 on division by zero.

u32_to_i32_saturating

Saturates a u32 to the range representable by i32.

u64_to_f64

Converts a u64 to f64 with the same rounding as Rust’s native cast.

usize_to_f64

Converts a usize to f64 with the same rounding as Rust’s native cast.

usize_to_u32_saturating

Saturates a usize to the range representable by u32.
