The modulus of a negative number is found by ignoring the minus sign. If you feel comfortable lets move on reading. Example include int main int a 7 b -10 c 2.

If we have negative numbers the result will be based on the left operands sign if the left operand is positive the result will be positive and if the left operand is negative the result will be negative. Note also that the modulus of a negative number can be found by multiplying it by 1 since for example 8 8. Int length 4.

G languages begingroup One way to get a feel for negative_value mod positive_value is to keep adding the modulus until you get a value 0. This simple optimization is not possible for languages in which the result of the modulo operation has the sign of the dividend including C unless the dividend is of an unsigned integer type. For example 8 -3 8 -3 trunc8-3 8 -3 trunc-2666.

Its quick easy. Can a modulus be negative. In the case of m 8 the q 2 and r 4 because 8 6 2 4.
