Modulo operation with negative numbers

Question

In a C program i was trying the below operations(Just to check the behavior )

 x = 5 % (-3);
 y = (-5) % (3);
 z = (-5) % (-3); 

printf(\"%d ,%d ,%d\", x, y         


        

Answer 1

Modulus operator gives the remainder. Modulus operator in c usually takes the sign of the numerator

1. x = 5 % (-3) - here numerator is positive hence it results in 2
2. y = (-5) % (3) - here numerator is negative hence it results -2
3. z = (-5) % (-3) - here numerator is negative hence it results -2

Also modulus(remainder) operator can only be used with integer type and cannot be used with floating point.
