invalid operands of types int and double to binary 'operator%'

Question

After compiling the program I am getting below error

invalid operands of types int and double to binary \'operator%\' at line 
\"newnum1 = two % (double)10.0         


        

Answer 1

Because % only works with integer types. Perhaps you want to use fmod().

Answer 2

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

Answer 3

Yes. % operator is not defined for double type. Same is true for bitwise operators like "&,^,|,~,<<,>>" as well.
