gcalc
gcalc is a plaintext calculator that understands expressions as you type them.
Some features you'll enjoy:
- You can type expressions (not like Windows Calculator, which is more like a table calculator pushing numbers)
- Can be used for "Programmer Nerd Type" expressions such as hex numbers or bit shifts.
- Can be used with variables (see example above)
- Remembers what you did: when you close it and start it back up again, it should bring back the last calculations

Starting with version 3.0, gcalc is part of gtools, which you can download here..
