# JavaScript to figure percentage

Posted on 2014-11-06

I have 4 Labels.
Label1 will always have a value of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 though this value will ultimately represent a percent.

Label2 will always have a whole number value (0-infinity).

Label3 is also always going to be a whole number, and should be a result of the value of label2 times the value of .1, .02, .03, .04, .05, .06, .07, .08, or .09 (and always rounded up when needed. Basically I'm trying to figure out a percentage.

Label4 is just the value of Label3 + the value of Label2

For example:
Label1 = 4
Label2 = 60
Label3 should equal "3" (60 * .04 = 2.4...rounded up is 3)
Label4 should be 63 (Label2 is 60 + Label3 which is 3 = 63)

Any mathletes out there wanna give it a shot?
TIA

The percentage of 'x' in 'y' is "(x/y)*100".  I don't see where your data is going to get that for you.

Independently:
Your answer is for Label3 = Math.ceil((Label1/100)*Label2)
Your answer is for Label4 = Math.ceil((1+(Label1/100))*Label2)

Dependently:
Your answer is for Label3 = Math.ceil((Label1/100)*Label2)
Your answer is for Label4 = Label2 + Label3

Dave, technically the percent is given (Label1) so I suppose the title was slightly misrepresented. In my example Label3 is "3" because the given paramater (Label1) is "4" and the other given paramenter (Label2) is 60. 60 * 4% is 2.40. Since we're rounding up no matter what, the answer (Label3) is "3".

And Label4 is just Label2 + Label3

Sorry for the confusion, that makes sense.

Here's what I'm currently doing on the server side if it helps to make sense.

``````        If lblPercentOveralge.Text <> "0%" Then
If lblFinalOrderQuantity.Text <> "0" Then
Dim strPO As String = ".0" & lblPercentOveralge.Text.Replace("%", "")
If lblPercentOveralge.Text = "10%" Then
strPO = ".1"
End If
Dim intPO As Decimal = Convert.ToDecimal(strPO)
Dim intAQ As Integer = Convert.ToInt32(lblFinalOrderQuantity.Text)
Dim intOQ As Double = Math.Ceiling(intAQ * intPO)
lblOverageQty.Text = "(+" & intOQ.ToString & ")"
Else
lblOverageQty.Text = "(+0)"
End If
Else
lblOverageQty.Text = "(+0)"
End If
lblActualProductionQuantity.Text = Convert.ToInt32(lblFinalOrderQuantity.Text) + Convert.ToInt32(lblOverageQty.Text.Replace("(+", "").Replace(")", ""))
``````

I'm trying to replicate this process on the client side.

But I already gave you the code? You never tried it?

My apologies. I wasn't aware you could do

``````Label3 = Math.ceil((Label1/100)*Label2)
``````

in JavaScript. I'll try it today.
