# 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.
