ToHost Convert a softfloat type to its corresponding hostfloat type. ToSoft Convert a hostfloat type to its corresponding softfloat type. 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.
