Usage: ccalc [-form FORM] [-eval 'expr']
Usage mode 1: Interactive numerical calculator
Interactive numerical calculator, using the
same expression syntax as 3dcalc.
No command line parameters are permitted in
usage 1 mode.
Usage mode 2: Command line expression calculator
Evaluate an expression specified on command
line, return answer and quit.
Optional parameters: (must come first)
-form FORM: Format output in a nice form
Choose from:
double: Macho numbers (default).
nice: Metrosexual output.
int (or rint): Rounded to nearest integer.
cint: Rounded up.
fint: Rounded down.
%n.mf: custom format string, used as in printf.
format string can contain %%, \n and other
regular characters.
See man fprintf and man printf for details.
You can also replace:
-form int with -i
-form nice with -n
-form double with -d
-form fint with -f
-form cint with -c
Mandatory parameter: (must come last on command line)
-eval EXPR: EXPR is the expression to evaluate.
Example: ccalc -eval '3 + 5 * sin(22)'
or: ccalc -eval 3 +5 '*' 'sin(22)'
You can not use variables in EXPR
as you do with 3dcalc.
Example with formatting:
ccalc -form '********\n%6.4f%%\n********' -eval '100*328/457'
gives:
********
0.7177%
********
Try also:
ccalc -i 3.6
ccalc -f 3.6
ccalc -c 3.6
ccalc -form '%3.5d' 3.3
ccalc -form '**%5d**' 3.3
ccalc -form '**%-5d**' 3.3
** SECRET: You don't need to use -eval if you are
not using any other options. I hate typing
it for quick command line calculations.
But that feature might be removed in the
future, so always use -eval when you are
