DECIMAL or NUMERIC
DECIMAL[(p[,s])]
DEC[(p[,s])]
NUMERIC[(p[,s])]
NUM[(p[,s])]A packed decimal number with an implicit decimal point. The position of the decimal point is determined by the precision (p) and the scale (s) of the number.
The p specifies the total number of the digits. The range of the precision is 1 to 31 digits.
The s is the number of digits in the fractional part of the number. It cannot be negative or greater than the precision. The range of scale is 0 to the precision of the number.
If p is omitted, the default is 5.
If s is omitted the default is 0, that is, values will have no decimal point or fractional part.
The range of a decimal variable or the numbers in a decimal column is -n to +n, where the absolute value of n is the largest number that can be represented with the applicable precision and scale. The maximum range is -10^31+1 to 10^31-1.
