ceilToDouble abstract method Null safety

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
