I think I’ll start using it!

How many years is 1,000,000,000 seconds? pcalc 1*10**9 / 60 / 60 / 24 / 365 31.7097919837646 31.7 years. Here’s the perl script I use for calculations:

while () {
print (eval $_);
print “\n”;
die $@ if $@;
}

Type in any legal formula ( or any perl statement for that matter) and get the results.

eg. How many years is 1,000,000,000 seconds?

pcalc
1*10**9 / 60 / 60 / 24 / 365
31.7097919837646

31.7 years.

I have it set to open on which is less typing and fast to come up them using SQL*Plus. Though, the history, and scriptability is quite nice. If i were on a Un*x box, i would think the script would be a simpler $bc... IMO, calc is faster when shortcutted.

Until now I though that I was the only lazy guy around doing stuff like this via his SQL*Plus terminal. ;-) LOL
