pub fn san<B: Backend, const D: usize>(t: &F<B, D>)Expand description
Primitive analogue of crate::modules::sanity for F.
Panics if t contains a NaN (when crate::DENY_NAN is set) or an Inf
(when crate::DENY_INF is set). A no-op — with no device read — when both
flags are false (the default), so it can be sprinkled through the backward
math at no release-build cost.
