For years, I've been wondering: How do other Unix or Linux users do simple<br>
calculations?<br>
<br>
Do you take out an actual physical calculator (which is of course ridiculous)?<br>
Do you use software that looks like a physical calculator (xcalc, kcalc, etc.)?<br>
<br>
Or do you use bc? Does anyone actually use bc, which returns "0" as a result<br>
for the calculation "2/3"? :-) Of course, you can use "scale=10" (or the -l<br>
option to bc) to fix that, but how many first-time users would know that?<br>
What posessed the person who decided to make scale=0 the default? :-)<br></blockquote><div><br></div><div>Indeed this is why I rarely use bc (and I am sorry when I do). For most purposes (that is, if I do not need a math function, which is not loaded when no executable is loaded), I use gdb.</div>

What I have been using myself, is my own version of Kernighan & Pike's "Hoc"<br>
(see <a href="http://nadav.harel.org.il/homepage/hoc/" target="_blank">http://nadav.harel.org.il/homepage/hoc/</a>). But since this didn't catch on,<br>
as didn't the original Hoc (which was available in Research Unix and Plan 9,<br>
but not anywhere else), unfortunately I'm one of the few who do. All of the<br>
rest are missing on the convenience of Hoc ;-)<br>
<br>
So I was wondering - how come there isn't more pressure on the Linux<br>
distributions to include a decent and convenient calculator language?<br>
Or do people consider what is available decent enough already?<br>
