## DECIMAL
### Description
DECIMAL (M [,D])
-High-precision fixed-point, M stands for the total number of significant
numbers (precision), D stands for the maximum number of decimal points (scale)
-The range of M is [1,27], the range of D is [1,9], in addition, M must be
greater than or equal to the value of D. The default value of D is 0.

DECIMAL(M[,D])
- 高精度定点数，M代表一共有多少个有效数字(precision)，D代表小数点后最多有多少数字(scale)
- M的范围是[1,27], D的范围[1, 9], 另外，M必须要大于等于D的取值。默认的D取值为0
