Pascal - MOD help needed

[Joseph]

Hey,

I have a test tomorrow on pascal and can't quite grasp the MOD function in pascal.

-100 MOD 8 = -4

I thought it was the remainder? -100/8 = 12.5 answer = 5?

Can someone clarify?

Maybe this would help? http://www.merlyn.demon.co.uk/pas-math.htm#DivMod

that link is kinda crptic.

MOD ( % ) is just remainder when you do long division.

so 13 % 10 is 3 (because 13 divided by 10 is 1 remainder 3)
and 5 % 2 is 1 (because 5 divided by 2 is 2 remainder 1)

MOD has lots of uses, for example it can test to see if a number is even or odd

if ( variable % 2 == 0) number is even


i took pascal in junior high, i cant believe they still teach it. Good luck mate.



(in your example, remember there are no decimals in long division)
