Compile-time math needs to be as correct as possible. RUN-time math can worry
about performance. The whole point of computer programming is to let the
machine do the hard work up front.
Regarding optimizations for speed at the expense of mathematical correctness,
they need to default to Off, and be switchable to ON for compile-time math.
Runtime math *maybe* could default to On, but since this is a change in
correctness for program output, it needs to be announced as a much bigger deal
as far as source-compatibility with existing code.

this would result in less efficient code, since all the math will then be done
at full precision, which is slower. it is a trade-off between size (=precision)
and speed.
[in] compile time math, performance doesn't count
