[REQUEST]Factorial Calculator?

[Joe Walls]

How would I make a factorial calculator using

1 textbox(txtInput)

1 fixed textbox(txtOutcome)

1 button(cmdCalculate)

 

I'm not sure how I code the but I know this will make a multiply function.(if I made a secon textbox)

 

txtOutcome.text = txtInput1.text * txtInput2.text

 

That's pretty much what I know bout calculators except I can add subtract and divide also

It's relatively difficult to create a calculator with 1 textbox. I didn't learn it until grade 12, but it was rather easy since I had a year of experience.

 

I'll upload some sources later today I made at school. They are in VB6 though.

Factorial should be pretty easy since you only need a number as an input

Here is an example of a factorial calculator. If the answer is above 18446744073709552000 it won't work because that is the maximum size of a ulong. So as long as you use it to calculate the factorials of numbers below 60ish you should be good.
