# actuarialangle

This package defines a single command `\actuarialangle` to typeset
nice looking "angles" in actuarial and financial notation, such as in
symbols for the present value of an annuity.

## Licence

Public Domain

## Author

The code in this package was given to me (Vincent Goulet
<vincent.goulet@act.ulaval.ca>) by a former colleague who would simply
copy it in the preamble of all his documents needing an "angle"
symbol. The actual author of the code is unknown.

My sole contribution was to make a package out of the code.

## Installation

The package is part of TeX Live and MiKTeX. If it is not already
installed on your system, copy `actuarialangle.sty` where LaTeX can
find it.

## Usage

Load the package as usual with

    \usepackage{actuarialangle}

Then, in math mode, use

    \actuarialangle{n}

to typeset "angle n". For a complete present value symbol, use
something like

    a_{\actuarialangle{n}}

You will most likely want to use the following shortcuts:

- `\angl`  for `\actuarialangle`
- `\angln` for `\angl{n}`
- `\anglr` for `\angl{r}`
