and then allocate the final string and copy result there)

a1415c0d72 bug in order NaN x int (tests must ensure that NaN does not get 
converted to integer)

ed1fe28bb8 When comparing integers with floats, use float as common type when 
possible (i.e., when integer fits in a float without losses); seems
to be more efficient in architectures with native support for used
Lua numbers
