Adds support for numeric casting operations,
[u24]
,[i24]
,[f24]
.Fixes #322.
Casts are always defined, and spiritually follow rusts numeric casting semantics:
i24 <-> u24
is just reinterpretation of bits.f24 -> i24
orf24 -> u24
casts to the "closest" integer representing this float, saturating if out of range and0
ifNaN
.i24 -> f24
oru24 -> f24
casts to the "closest" float representing this integer.
