..I guess you mean eval()

int/float should be faster because eval creates an intermediate code
object which is then executed by the bytecode interpreter. eval has the
advantage that it automatically distinguishes between ints and floats,
though, and other literals and even expressions for that matter.

It is, of yourse a gaping security hole unless you use rexec.
