Ratio Formula

Hello, i've done a search and found this topic:

http://www.vbforums.com/showthread.p...=ratio+numbers

I'm trying to find and most importantly understand a formula for calculating the ratio between 2 numbers.

The example in the thread above gives me the answers, but im confused about what its doing. The strangest being this:

If (val_1 / min_val) = (val_1 \ min_val) And (val_2 / min_val) = (val_2 \ min_val) Then

What is the difference between the forward facing '/' and the backwards facing '\' as they sometimes give different results. Maybe if i understood what they were doing i could get the rest.

In my opinion, val_1 Divided by min_val will always equal val_1 Divided by min_val.

By the way, my code is actually in Java, but i'm reasonably happy converting it to java myself.

Thanks for any help!

/ is standard division which returns a double
\ is integer division and only returns the integer part of a division result.

e.g.
2 / 3 = 0.666666666...
2 \ 3 = 0

a comparison like (val_1 / min_val) = (val_1 \ min_val) is checking to see if the result of the division is an integer.

thanks bushmobile!! Thats cleared things up a lot. I'll post again if i get confused anymore. :)

Quick reply too, nice one!

More examples:
Int(2/3) = 2\3 = 0
Int(3/2) = 3\2 = 1
4\2 = 4/2 = 2

You can thus use this feature for a nice comparison:

If N/2 = N\2 Then ' you know that N is evenly divisible by 2 and thus an even number. Otherwise, it's odd. :cool:

Seems i'm having quite a few problems and i go back on my word now. Just wondered if anyone could help me convert this code to java? I've started a new thread about this over in the java forums:
