truncateToDouble method

double truncateToDouble ()

Returns the double integer value obtained by discarding any fractional digits from the double value of this.

If this is already an integer valued double, including -0.0, or it is a non-finite double value, the value is returned unmodified.

For the purpose of rounding, -0.0 is considered to be below 0.0. A number d in the range -1.0 < d < 0.0 will return -0.0, and in the range 0.0 < d < 1.0 it will return 0.0.

The result is always a double. If this is a numerically large integer, the result may be an infinite double.
