calculating percent from total

[bcardona]

it has been a while since i did this and dont remember, how to take say 10% of a total price, your help is appreciated

Multiply by 0.1 ?

Is this a trick question?

 

[bcardona]

no not a trick question, its been a while since i did classic asp, dont take the numbers i used literally, heres an example.

if a product is $25.00 and the percent off is 6% what is the total.

 

[bcardona]

sorry i was told wrong what i need is, say a product is 12.99 but will sell for 10.50, what percent did they save.

 

[JohnYingling]

((12.99 - 10.50) / 12.99) / 100 = %

do i have to use formatcurrency or anything like that

 

[Sheco]

That depends on how you want it displayed.

 

[bcardona]

what i am trying to do, is for instance we have a product say for 11.99 then it says buy now for 8.50 then it says you saved whatevery percent, this is what i need to have it say as an example 30%, i think i have the calculation right, im not sure if some already has it done and would pass it along i would appreciate it, also i cant remove the decimal from the percentage here is my code for the percent

formatpercent(variable,2) it displays .12%. thanks in advance

The various functions that you need are all referenced in detail at

http://msdn2.microsoft.com/en-us/library/d1wf56tt(vs.71).aspx

To save you looking them up try

<p>Normal price 10.99 - our price 8.50 - you save <%=round(100*((10.99-8.5)/10.99),0)%>%</p>

Use that and the reference site, along with the previous answers to work out how it all works. If you have any more questions read faq222-2244 for guidance on forum usage and basic research, then post again.

You could make a function:
makePriceLine()

It could accept price a, price b, discount

Then you could have the logic:

IF price a and price b are set:
check difference and calculate if there is a discount

IF price a is set or price b is not set and discount is set:
calculate price and give discount

RETURN:
price a (inside a span with css style strike-through and red font)
price b
discount
