modulus

Question

how does 7 mod 8 equal 7?
my math is 7/8= .87 which rounds up to 1.
Why would the answer not be 1?

Is it because your left with 1 and that 1 -8=7?

Answer 1

Modulus isn't attempting to round up a decimal, it looks to return a natural number.
8 does not divide into 7 so you get a return of 7.
If you were dividing 8 into 9, you would get a return of 1 using modulus

Answer 2

Modulo operator gives you remainder... So 7/8 gives quotient as 0 as it's integer division and remainder 7
