need serious beginner help

[Jimbo]

Just got this wacky program because I always thought it was fun to make things on my graphing calculator. I was just trying to make this program about the standard formula for a line and I can't get the thing to work! It's been driving me nutty and any help would be greatly appreciated!

If OpenConsole()
PrintN(""):PrintN("Input A: ")
a.s=Input()
StrF(a)
PrintN(""):PrintN("Input B: ")
b.s=Input()
StrF(b)
PrintN(""):PrintN("Input C: ")
c.s=Input()
StrF(c)
xintercept.f=(c/a)
yintercept.f=(c/b)
ClearConsole()
PrintN("The X-intercept is "+Str(xintercept)+"and the Y-intercept is "+Str(yintercept)+".")
EndIf
End

Sincerely,
Jim

there is a few problems with your code,

StrF() returns the string version of a value. you want ValF(), that takes a string and extracts the floating point value from it

you need to assign the ValF() output to a varible it doesn't

Code: Select all

If OpenConsole()
PrintN(""):PrintN("Input A: ")
a.s=Input()
af.f = ValF(a)
PrintN(""):PrintN("Input B: ")
b.s=Input()
bf.f = ValF(b)
PrintN(""):PrintN("Input C: ")
c.s=Input()
cf.f = ValF(c)
xintercept.f=(cf/af)
yintercept.f=(cf/bf)
ClearConsole()
PrintN("The X-intercept is "+Str(xintercept)+"and the Y-intercept is "+Str(yintercept)+".")
EndIf
End

Hey, thanks a lot. Very commendable of you to spend your time. I hope you have a nice fortune soon!

It's hard to find thorough turorials for PureBasic. How did you guys figure this stuff out in the first place? It all seems very strange!

The help file and experimentation! Not to mention many of us have lots of programming experience in other languages.

Also, there is such helpful thing as MilliHelp - reference cards/diagrams for PB functions, that help to see the needed function at a couple of glances.

but a. it's not for pb4 appearently, and b. it's a commercial product

<sarcasm on> next thing will be paul telling the world that with purevision you don't need much help at all... <sarcasm off>
