Constructor Detail

DecimalType

public DecimalType(int precision,
                   int scale)

Creates a decimal type with precision and scale.

Examples:

• 123.45 has precision 5, scale 2.
• 12,345,000 has precision 5, scale -3.

The largest value is 10 ^ (precision - scale). Hence the largest DECIMAL(5, -3) value is 10 ^ 8.

Parameters:

precision - Maximum number of decimal digits which a value of this type can have. Must be greater than zero. Use Integer.MAX_VALUE if the precision is unbounded.

scale - Number of digits to the right of the decimal point.

getScale

public int getScale()

Returns the number of digits to the right of the decimal point.

Returns:

number of digits to the right of the decimal point

toString

public String toString()

Overrides:
