QuickCalc v1.26 - An interactive calculator equivalent to a TI-30ish
calculator.
This archive includes two programs. Qc is an interactive calculator that
can do most everyday stuff. Xqc is the X windows frontend to qc. Qc must be
installed to use xqc. To find more out about what qc can do, type
"help <enter>" and then choose a topic from the list, after running qc.
Requirements:
To compile qc you will need libreadline, and flex. Readline can be
found on sunsite.unc.edu in the /pub/Linux/libs/ directory. Xqc
requires the xforms library, which can be found in the /pub/Linux/X11/devel/
directory. After making sure you have installed both libraries and looked
over the Makefiles in the qc-1.01 and xqc-0.2 directory do:
make
su
make install
This will install the programs in /usr/local/bin.
There are four basic ways to use qc:
1) Interactively - Start qc by typing "qc". Then enter any expression and
hit enter to find out the answer. ex: "2+2 <enter>" will yield "4".
2) Command Line - Start qc with "qc -e '<EXP>'" where <EXP> is something
like "asin(sin(%pi/2))". qc prints the answer and exits.
3) Redirected Input - Start qc with something like "qc -p <test", where test
is a file containing any number of valid lines of input. The p option tells
qc not to print out its prompt before each answer.
4) The X-Windows frontend - Run xqc. This pops up a nice looking calculator which
looks and works like any other calculator.
NOTE: Xqc must be able to find qc in the standard PATH or it will crash with
a 'Broken Pipe'.
