The storage required for a DECIMAL data type is potentially much larger than it is for a normal floating-point data type.
DECIMAL数据类型需要的存储空间通常要比浮点数据类型大得多。

The only time floats are used is in manipulation of large multidimensional arrays of floating-point numbers with limited precision in which the storage space would be significant.
使用 float 的惟一时机就是操纵精度有限的大型多维浮点数字数组，此时存储空间较为重要。

Combined, they offer a single point for serving the Floating, Production, Storage and Offloading segment.
