The double type can also be referred to as double precision, although it isn't clear why you would want to type the extra word every time you need a double-precision number.
double类型也可以表示为DOUBLE PRECISION，虽然为什么在需要双精度数字时要输入额外的单词，原因不明。
Of course, if you really do need the extra precision, then you'll need to pick a data type with more precision, such as a double or a BigDecimal.
当然，如果一定需要额外的精度，则可以选择具有高精度的数据类型，比如double或BigDecimal。
The temperature control is achieved by the microcomputer intelligent type double display and PLC temperature controller which can be set up, thus the temperature control precision is reliable.
