NAME
rpncalc - a reverse polish notation (RPN) calculator.SYNOPSIS
rpncalc [-h]|[-v]|["expression"]DESCRIPTION
rpncalc partially emulates a HP 28S and is intended for every-day purposes (i.e. 1 1 +), not for complex calculations (use gnuplot(1) or octave(1) for these). rpncalc evaluates expression if given or reads from standard input otherwise. These features are not implemented:• complex numbers,
• vector, matrices, lists and arrays,
• algebraic input, symbolic evaluation,
• units, and
• variables.
rpncalc recognizes the following functions, operations, and constants:
! | % | %ch | %t | & | * | + | - |
/ | ? | ^ | abs | acos | acosh | alog | and |
arg | asin | asinh | atan | atan2 | atanh | bin | cbrt |
ceil | char | chs | clear | cos | cosh | dec | depth |
div | drop | drop2 | dropn | dup | dup2 | dupn | erf |
erfc | exit | exp | expm | fact | floor | fp | gcd |
help | hex | hypot | inv | ip | j0 | j1 | jn |
ld | ldb | lg | lgamma | ln | lnp1 | log | max |
min | mod | neg | not | oct | or | over | pick |
pop | prec | prod | push | quit | rand | rdz | rint |
rnd | rot | shl | show | shr | sign | sin | sinh |
sl | slb | sq | sqr | sqrt | sr | srb | sum |
swap | tan | tanh | warranty | xor | y0 | y1 | yn |
| | ~ |
Delimiters are ,, ;, space, tab and newline.
A few things have been added with respect to a HP28: the prefixes 0x resp. 0 stand for hexadecimal resp. octal constants, as in C. The Bessel Functions and the error functions are new, in order to make better use of the math library.
OPTIONS
- -h, --help
- stands for help
- -v, --version
- prints out the current version of rpncalc and exits.
SEE ALSO
dc(1), bc(1), gnuplot(1), pari(1), octave(1), units(1).BUGS
The floating point exception handling relies on the math library and is site- and architecture dependent.Accuracy and range of the calculations is at the mercy of the math library (and generally much worse than the original).
