That's not always the truth, Lua make extensive use of floating point,
so it is advisable to use integer as numbers for those CPU who do not
have hardware floating-point support.

Also, some CPUs do not support floating point at all and cannot
compile lua without any modification.

Generally, I compile lua with floating point only for x86 cpus which
have SSE support. for ARM and MIPS cpus it is better to use integer as
numbers.
