Macro. Provides an argument for functions specifying 64-bit (8-byte) double-precision data type.
writes the series in the current Window to a file named MYFILE as 64-bit IEEE standard double-precision floating point values. The above example is equivalent to writeb("MYFILE",7).
DOUBLE is not a stand-alone Worksheet function. It can only act as an argument for functions, such as READB, WRITEB, and other functions with data type arguments.
When writing a file using DOUBLE as the file type be sure to read the file back into the Worksheet using the same binary format.
