rpncalc(1)

Usage

rpncalc {[-h] | [-v] | ["expression"]}

Overview

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.
