# gc

This is an extremely simple interface to the Google Calculator. Just pass it the query on the command line.

    $ gc 2 + 2

    4

    $ gc -v 2 + 2

    2 + 2 = 4

    $ gc once in a blue moon

    1.16699016 * 10^-8 hertz

    $ gc "(4 * pi * epsilon_0 * hbar * c) / elementary charge^2"

    137.035984

    $ gc "sqrt((c * 8 minutes)^3 / (G * m_sun)) * 2 pi in years"

    0.943428231 years

Alternatively you can use `gc` interactively:

    $ gc

    >> 1m / (2 second / 2 pi)^2

    9.8696044 m / s^2

    >> 4 pi * r_earth^2 in inverse barns

    1.95617402 * 10^-43 inverse barns

**NB:** This is particularly nice when combined with [rlwrap](http://utopia.knoware.nl/~hlub/uck/rlwrap/rlwrap.html), as `gc` has no readline support of its own.

## Why use gc?

The big difference between this and other projects such as [uj-gcalc](http://code.google.com/p/uj-gcalc/) is that it doesn't try and parse the results from the Google HTML results page, it extracts them directly from the Calculator API at , thus hopefully making it more resilient to the whims of Google's engineers.
