Hi! I'm new to using SMath, and I've run into what might be a glitch.

This: [math]f(x):=x*10^-15[/math] won't calculate, giving an error "1E - not defined" for any value of x. Is this just a precision problem with variables in the program?

It seems it is corrected. This is from the SMath Live:
[LIVE width=216 height=257]http://smath.info/live/?file=590[/LIVE]
This is obtained from SMath-Live, inserting some expressions and copying the link from there into this post ("quote" this message and you will see it)
Play with it.

Regards,
Radovan

P.S. Pay attention on your Regional settings (see the posts about it). What is the decimal separator (point or comma) and what is the function argument separator (comma or semicolumn)

I remember this error. It was some time ago and it is fixed now. I just don't remember in what version it was fixed... so, if you are using the latest SMath Studio 0.82, then, please, tell me what version you need (Desktop/DesktopPortable/DesktopLinux/Handheld) and I will create fixed setup files for you.

Best regards, Andrey Ivashov.

Oops, I should have mentioned what version I was using in my original post.

I'm using the Desktop version 0.82 build 3477, on WinXP SP3.

Thank you!
