Description:
------------
This issue has been brought up before, but not in so many words.

The modulus operator (%) truncates float operands and always returns an integer result. Some languages behave similarly, some do not. Java, for one, correctly performs the float calculation.

I see no reason--besides ease of coding or perhaps for the sake of efficient code--that such an arbitrary limitation would be placed on a general mathematical operator. Some limitations, like disallowing division by zero, are not arbitrary; these are required mathematically. However, restricting modulus to integer operands is not mathematically logical.

You may make the suggestion that I write my own float modulus function that performs recursive subtractions. However, if your reason for coding mod as an integer operator is efficiency, writing <i>script</i> code to perform this calculation--especially on large numbers--is most certainly not more efficient.

I (humbly) request that you reconsider the way you've coded the mod operator.

Reproduce code:
---------------
print(4.5 % 2);


Expected result:
----------------
.5

Actual result:
--------------
0
