# ceilToDouble abstract 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`.

    print(1.99999.ceilToDouble()); // 2.0
    print(2.0.ceilToDouble()); // 2.0
    print(2.00001.ceilToDouble()); // 3.0
    print((-1.99999).ceilToDouble()); // -1.0
    print((-2.0).ceilToDouble()); // -2.0
    print((-2.00001).ceilToDouble()); // -2.0

## Implementation

    double ceilToDouble();
