trunc(x) and trunc(x,y)

[Former user]

Originally reported on Google Code with ID 40

Add trunc(x) function, aliasing to int(x). This is because some calculators
use trunc and others use int, there's no standard terminology, so support both.

``` Let's change this a bit:

trunc(x) -> int(x) trunc(x,0) -> trunc(x) trunc(x,y) -> <int(x)>.<y-digits>

y = (non-negative) number of decimal digits to the right

See http://en.wikipedia.org/wiki/Truncation ```
