# NAME

Bot::Cobalt::Plugin::Calc - Calculator plugin for Bot::Cobalt

# SYNOPSIS

   # See Math::Calc::Parser ->
   !calc 2 + 2
   !calc 0xff << 2
   !calc int rand 5

# DESCRIPTION

A [Bot::Cobalt](https://metacpan.org/pod/Bot::Cobalt) calculator plugin using [Math::Calc::Parser](https://metacpan.org/pod/Math::Calc::Parser).

See the [Math::Calc::Parser](https://metacpan.org/pod/Math::Calc::Parser) documentation for details on acceptable
expressions.

# CAVEATS

This plugin uses a "safe-ish" forked worker to do the actual calculations,
with resource limits in place to avoid denial-of-service attacks via large
factorials and similar; however, not all platforms support all relevant
[BSD::Resource](https://metacpan.org/pod/BSD::Resource) rlimits, in which case it may be possible to force the bot to
perform very large calculations.
