Check decimal precision of Floating points

Question

I want to validate that a float or Double has minimum 5 numbers after decimal points.This is the code I have written

private boolean invalidDecimalPrecision(Double point)
{
    int decimalPrecision = BigDecimal.valueOf(point).scale();

    return !(decimalPrecision >= 5);

}

Is it good enough or do I have to handle specific case of negative scale numbers as well

Answer 1

The plugin which generates Pojos has accepted the feature request for adding an option to represent Double as BigDecimal
