How do I check if x can be represented as a float? For example, for

What if x is a float?
print(x == (x+0.0))

If you need to distinguish integers from float, you can use math.type(x).

But please share why you need all this.

To check types? I guess that because Lua converts int to float without caring about precision loss (¬_¬) I don't need this, so meh... (only noticed now)
