# Ralcalc 1.3.2

Command-line calculator

Ralcalc is a simple command-line calculator software designed to take a single line input and produce a result.

Both the input and output make use of SI prefixes (see http://en.wikipedia.org/wiki/SI_prefix) for easier input and reading of results. Only the common engineering prefixes that are powers a multiple of three are used, so G, M, k, m, u, n, etc.

Numbers of the style 1e-3 are also supported for input.

Version information can be shown with:

* + Addition

* - Subtraction

* * x Multiplication (the 'x' is for use when shell expansion may be a problem)

* / Division

* ^ Power

* [] Brackets - increase the precedence of anything within the brackets.

* _ The result of the last ralcalc run (stored in $HOME/.ralcalc_result)

* log The base 10 logarithm.

* ln The natural logarithm.

* sin, cos, tan, asin, acos, atan

* sqrt

* pi (3.14159)

* exp (2.71828)

= 2^.5

2^.5 = 1.41421

= 1/_

1/_ = 707.107m

**For example:***= 2*9*

2*9 = 182*9 = 18
