Conversion Help Needed

I want a user to enter either a decimal or percentage, but the program must convert the percentages into decimals. How do I go about doing this? Whenever I attempt this, my program converts all numbers inputted. Can someone help me??

Thanks

Show us the code you have.

Here's what I have so far...
code:

%Investment program
var investment, interest : real
var term : int
var plan : string
locate (12, 29)
put "Cash Investment Program"
delay (5000)
cls
put "Please enter your cash investment: $" ..
get investment
cls
put "Please enter your interest rate: %" ..
get interest
if interest >= 0 then
    interest := interest / 100
elsif interest >= 0.00 then
    cls
end if
cls


I know that code under "get interest" is wrong. How do I make it so that when the user inputs a decimal, the program will leave the number alone, but when the user inputs a percentage, the program will convert it to a decimal?

Thanks

The program is supposed to take the interest and if the user inputs a percentage, then the program must convert it into a decimal. If the user inputs a decimal, then the program should keep the decimal as it is.

By declaring "interest" as "real", you ensure that it will always be a decimal number. There's no need for conversion.

you should really give name to your variables espially in long code (make it ezer for ppl to read n figure out wut they mean or do
