Modulus division returns an integer?

Question

Does modulus division only return integers? I need a float return. See the following:

var_dump(12 % 10); // returns 2, as expected
var_dump(11.5 % 10); // returns 1 instead of 1.5?

Answer 1

Yes. the % operator returns an integer.

If you want a floating point result, use the fmod() function instead.

Answer 2

See the manual.

Operands of modulus are converted to integers (by stripping the decimal part) before processing.

11.5 becomes 11.

11 % 10 = 1 remainder **1**

Your solution: fmod(), as tom_yes_tom suggests.
