Find percent of a number

[James]

Hey,

I have been brushing up on my math skills (Im really not too good).

MsgBox(0, "Percent", Percent(10, 100))

Func Percent($number, $percent)
    $Multiply = $number * $percent
    $Divide = $Multiply / 100
    $Final = StringSplit($Divide, ".")
    Return $Final[1]
EndFuncoÝ÷ Ø
®É¯²ºÈ§íjëh×6MsgBox(0, "Percent", Percent(10, 100))

Func Percent($number, $percent)
    Return Int(($number * $percent) / 100)
EndFunc

Thanks SWG

Not to make you feel bad, but just to show you another way:

Func Percent($number, $percent)
    Return Int(($number * $percent) / 100)
EndFunc

The Int() function does what you were doing with stringsplit, but probably faster.

Cool, I learnt something new! Thanks SWG

pseudo-edit:

Dunno if it's the forum acting up or not, but I can't seem to edit my previous post.

The original function you posted yielded 5 percent when it should have yielded 20 percent (based upon my "10,50" example).

Actually, I think JamesB's original function wasn't trying to answer the question:

<number1> is what percent of <number2>?

I think it was trying to answer the question:

What is <number2> percent of <number1>?

So, both could be right, depending on what you were looking to answer.

[James]

SWG is correct, it finds the percentage of a number.

In the function, it looks at the first number in the function:

10 is the percentage of 100.

Thought so, and btw, the way your function is done, the order in which you put the numbers really doesn't matter, since multiplication will work with either number first.

Yeah, I just noticed I named them wrongly :\

Ah, that explains why it didn't look right.

[James]

Yeah sorry

I will change it.
