Right; IEEE 754 (2019) _recommends_ that correctly rounded transcendental functions be provided, but does not require it. The next revision of the standard may require that a subset of correctly-rounded transcendental functions be provided (this is under active discussion), but would still not require how they are bound in the language (i.e. a C stdlib might provide both `pow` and `cr_pow` or similar), and might not require that all functions be correctly rounded over their entire range (e.g. languages might require only that `cr_sin` be correctly rounded on [-π,π]). |
