[SOLVED] percentages...

[thefollower]

How do you make a set equation so that no matter what the % is or the value the answer will always work?

 

So say you have

 

$X = %

$Y = value

 

and your trying to subtract the $X % from $Y ?

[boushley]

So you want to subtract $x (which is a percent from ) $y.

 

So if

$x = 10 (assumed to be a percent)

$y = 100

 

Then after the equation $y should equal 90?  Is that what your going for?

If this is the case... then $y = $y*($x/100)

Or if you set $x=.10 then just $y = $y*$x

 

 

Or are you looking for something that if you enter a percent or a non percent it still works?

 

I'm kind of confused as to what you're looking for. Did that help? Is that what you're looking for??? ???
