Functions

apply_random_float_error 🔒

Disturbes a floating-point result by a relative error in the range (-2^scale, 2^scale).

apply_random_float_error_to_imm 🔒

Applies an error of [-N, +N] ULP to the given value. Will fail if val is not a floating point number.

apply_random_float_error_ulp 🔒

Applies an error of [-N, +N] ULP to the given value.

clamp_float_value 🔒

Given a floating-point operation and a floating-point value, clamps the result to the output range of the given operation according to the C standard, if any.

fixed_float_value 🔒

For the intrinsics:

fixed_powi_value 🔒

Returns Some(output) if powi (called pown in C) results in a fixed value specified in the C standard (specifically, C23 annex F.10.4.6) when doing base^exp. Otherwise, returns None.

host_unary_float_op

sqrt 🔒

sqrt_op

strip_float_suffix 🔒

Remove f16/f32/f64/f128 suffix, if any.
