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.

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.

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.
