Frustrated by the fact that you don't have the integer division operator in JavaScript?

Here's a surprisingly little known method:

parseInt(19/4) = 4

Now when a VBguru or vbscripter says "ha ha, I can integer divide and you can't!"

You now know better.

Division Problem

Ok, im not going to show the whole code, for various reason but what I do display should be enough

I am creating a program that will ask you how many people are on board the ship, how many people can fit in a lifeboat and how many lifeboats you have...
The program will then calculate the minimum amount of lifeboats you will need to get everyone safely off board....

Heres my problem....Say it you input there are 800 people on board and only 90 people can fit per lifeboat, so you got 800/90 = 8.88
But you can't have it display as 8.88 because you can't have .88 lifeboats lol
So instead of a double you make it an int, so it equals 8.... but you don't want it to equal 8 because then you'd be .88 lifeboats short, you want it to equal 9 so this is where IM truly stumped
Heres a sample code of what I have
Code:

int minLb = peopleNumber/peoplePerLifeboat;
		System.out.println("A minimum of " + minLb + " lifeboats are required to rescue everyone on board.");

And a sample of what it produces

"Number of people on board the hg:800
Maximum number of people per lifeboat:90
Number of lifeboats that are available on the hg:7
Here are the results...
A minimum of 8 lifeboats are required to rescue everyone on board.
any help is appreciated

Hi there. I have a program that generates a random exam with digits 0 -9.

I have managed to generate random symbols to appear inbetween each question and it now accepts an answer. What i need is that when a division sum is generated, i need another field beside the answer for the remainder.

Here is the code:
