How to split a decimal number in lua script?

I need to split the balance (decimal value) in to two part.

 Like 6678.9999  to
 6678 and 9999

So my final array will be value[0] = 6678 and value[1] = 9999

Is it possible in lua with decimal,I can do with string.

Can any one guide for me ?

The problem is, floating point numbers are usually not precise, due to the fact that computers use binary system. For example:

print(6678.9999 % 1)

The output is 0.9998999999998, not 0.9999.

So the best way is probably still string manipulation:

string.match(tostring(6678.9999), "([^.]*)%.([^.]*)")
