# ceilToDouble method

double ceilToDouble ()
override

Returns the least integer double value no smaller than `this`.

If this is already an integer valued double, including `-0.0`, or it is not a finite 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`.

## Implementation

    double ceilToDouble();
