In this case, what does the percentage refers to?
int myInt = 27 % 10;
myInt = 7;
What does the % mean in this code?

2It's the modulus operator. – Matt Ball Jul 18 '13 at 19:59

3`%` is remainder operator, @MattBall not modulus – Grijesh Chauhan Jul 18 '13 at 19:59

@GrijeshChauhan there's a difference? – Matt Ball Jul 18 '13 at 20:00

2@GrijeshChauhan Euh, do you speak English? – Jul 18 '13 at 20:01

1@iamnotmaynard Namely what? – Jul 18 '13 at 20:03

@iamnotmaynard : thanks! H2CO3 my English is poor, but point is its not modulus but remainder. – Grijesh Chauhan Jul 18 '13 at 20:03

1@GrijeshChauhan But they are the same... – Jul 18 '13 at 20:04

@H2CO3 +1 to your comment :) – Grijesh Chauhan Jul 18 '13 at 20:08

2@GrijeshChauhan Thanks! Now I'm just waiting for the explanation of iamnotmaynard. – Jul 18 '13 at 20:09

This question appears to be off-topic because it is about not putting any effort in – Tony Hopkinson Mar 06 '14 at 23:10

% means remainder, when 27 is divided by 10 leaves a remainder 7
EDIT:
My 2 cents about all the discussion about difference between modulo & remainder
Take a % b
1. When both +ve, Modulo & Remainder are one and the same
2. When a is -ve, they are not the same
For example;
a = -10, b = 3
Remainder of -10 % 3 = -1
for Modulo, add a greater multiple of 3 to your 'a' and calculate the remainder.
-10 + 12 = 2
2 % 3 = 2 is your answer

the % is modulus operator, not percentage. For percentage, you just do regular math. 50% is to multiply by .5... etc.
For future reference, the objective c mathematical operations are documented many places, including here.
Note the % is called "Modulo" operator.

The "%" in this code is called the modulus operator. This causes the processor to perform a division operation, and it returns the remainder of the division.
For example:
- 8 % 10 = 8
- 5 % 4 = 1
