What does (10%2) mean?

Question

What does the code (10%2) mean?

Please use a more descriptive question title next time--e.g. "What does % mean?" — Lèse majesté, Aug 21 '10 at 07:11
@Lese majeste So he should use a less descriptive, ambiguous title like "What does % mean?". % can mean a number of things, including percentage... — alternative, Aug 21 '10 at 17:56

% is the modulus operator.

So this essentially says - what is the remainder of 10 divided by 2?

10 % 2 == 0
10 % 5 == 0
10 % 7 == 3
10 % 3 == 1

10 modulo 2, or in other words, the remainder of 10 divided by 2.

10 % 2 is 0 because there is no remainder after you divide by 2.

10 % 3 -> this would divide by 3, which results in a remainder of 1 (10 = 3*3 + 1)

The modulus operator (%) computes the remainder after dividing its first operand by its second.

10 % 2 should give you 0. It is the MODULUS operator

10%2 is 0, 10 divided by 2, rest is 0. This can also mean that number is even.
