# Percentages

 P: n/a I have two textboxes. One is to enter the percentage rate, and the other text box is to enter the price of the item. What is the formula to get the correct answer after the percentage has been subtracted from the original price. Example: 10% of \$1 = .90 Thank you in advance, DAL. Feb 14 '06 #1

 P: n/a Try this. Dim prcnt as Integer = cint(txtPercent) Dim price as Integer = cint(txtPrice) Dim Xnum as Integer = (100 - prcnt )/100 txtFinalPrice.Text = price * Xnum Pretty much what your doing is subtracting the entered percentage from 100 and then dividing that from 100. Then multiplying that by the price. Example: 100% - 10% = 90% 90/100 = .9 ..9 X \$1 = .90 Hope this helps, Jeremy Reid http://blackstaronline.net/hgtit Feb 14 '06 #2

 P: n/a Sorry to butt in but . . . , you can't use integers to calculate percentages unless you significantly modify the approach.

 P: n/a Whoops, my bad, Thanks for catching that. Don is absolutely correct. Integer data type is NOT what you would want to use to calculate that equation. Sorry for leading you down the wrong path....my bad. Jeremy Reid http://blackstaronline.net/hgtit Feb 15 '06 #4
