gcalctool Functions

Slick666 · 09-16-2008, 07:58 AM

What I'm trying to do appears to be pretty straight forward. I use gcalctool all the time and I want to use the user defined functions to define some of my own constants and functions of simple calculations that I do over and over but for the life of me I can't seem to figure it out.

With every entry I get I get the error "Malformed Function". I've looked up the man page, the homepage of the project, and googled the error but no where can I find en example or a definition on how to form the functions. Can someone enlighten me on this please?

From the gcalctool help screen:

Quote:

The gcalctool application does not provide any default functions. You can store up to ten functions.

To store a new function or edit an existing function, perform the following steps:

1. Click Fun, then select Edit Functions from the popup menu.

2. In the Edit Functions dialog, select a blank entry, or the function that you want to overwrite.

3. Click on the Value field, then enter the new value. Use the keyboard shortcuts to invoke a gcalctool button. For example, enter 90K to calculate sine(90).

4. Click on the Description field, then enter the new description. For example, Sine 90.

5. Click OK to save your changes and close the Edit Functions dialog.

I've been trying to do the same thing myself (on 5.24.1), and you're right. There's absolutely nothing out on google. So I submitted a bug via the help menu. Well, the project hasn't used that specific bug tracking system for several years. So after some heavy investigative journalism, here's the bug-tracking page for the project:

http://bugzilla.gnome.org/browse.cgi?product=gcalctool

The 2 related bugs are in the Components => docs area. They're still not fully addressed yet. However, the key is adding an "=" after the statement. "sin(45)=" works properly, as does "sin(R0)=". R0 of course being a stored value.

It's a heck of a thread bump; but it was important to me, and it answers the question properly.
