# floorToDouble abstract method

double floorToDouble()
override

Returns the greatest integer double value no greater 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 `0.0 < d < 1.0` will return `0.0`.

    print(1.99999.floorToDouble()); // 1.0
    print(2.0.floorToDouble()); // 2.0
    print(2.99999.floorToDouble()); // 2.0
    print((-1.99999).floorToDouble()); // -2.0
    print((-2.0).floorToDouble()); // -2.0
    print((-2.00001).floorToDouble()); // -3.0

## Implementation

    double floorToDouble();
