The Java Language Specification uses the terminology from the IEEE 754 
floating point spec.  Java uses "round toward zero" as opposed to 
"round to nearest".  What it calls "round toward zero" is often 
referred to as truncation.

From JLS section 5.1.3:

    ... the floating-point value is rounded to an integer value V,
    rounding toward zero using IEEE 754 round-toward-zero mode
   (�4.2.3).

And section 4.2.3 says:

    The language uses round toward zero when converting a floating
    value to an integer (�5.1.3), which acts, in this case, as though
    the number were truncated, discarding the mantissa bits. Rounding
    toward zero chooses at its result the format's value closest to
    and no greater in magnitude than the infinitely precise result.
