Floats module in PHP returns integers?

Question

How do I get the rest of the division (operation module %) with decimal places when using a divisor or dividend float?

Example:

echo 5 % 3; // imprime 2 como é esperado
echo 5.6 % 3; // imprime 2 quando deveria imprimir 2.6

Answer 1

There is the possibility to use the function fmod ^{(in English)} which is appropriate for this. I don’t know if it will give the result you expect, but in my quick test it was ok.

Then you would:

echo fmod( 5.6, 3.0 );

This will print 2.6.

Behold working in the ideone and in the repl it.. And put on the Github for future reference.

Answer 2

The operator Module, server only for integers, for such use, you can use the function fmod of PHP:

fmod(5.6, 3); // imprime 2.6

If you only use the Module operator (%), the value obtained will be the Largest Integer Smaller than the result.

Answer 3

This operator only works with integers

There’s a comment on that link lembando this.

Note that the % operator (module) only works with integers (between -214748348 and 2147483647)...

Try using fmod()
