Ahemm, I _do_ word my postings carefully.
The ARM FP instruction set _does_ provide both rounding and
FIX reg, fpreg
FIXZ reg, fpreg
The fact that most ARM based systems don't have a (hardware) FPU
is something quite different and doesn't matter for the discussion
at hand. Because then you'd better use integers for lua_Number
which makes all the relevant casts a no-op.
