Details
The precision of numeric values can be controlled with the format.asciiprecision attribute. The
byte order of format.SREAL , format.REAL , format.REAL32 , and format.REAL64 can be
selected with the format.byteorder attribute.
REAL32 and SREAL select the same single precision format. REAL and REAL64 select the same
double precision format. They are alternative identifiers. Selecting which to use is a matter of
preference.
The IEEE Std 754 binary formats use four bytes for single-precision values and eight bytes for
double-precision values.
When data is written with any of the binary formats, the response message starts with
#0 and ends
with a new line. When data is written with the ASCII format, elements are separated with a comma
and space.
Binary formats are not intended to be interpreted by humans.
Example
format.asciiprecision = 10
x = 3.14159265
format.data = format.ASCII
printnumber(x)
format.data = format.REAL64
printnumber(x)
Output a number represented by x in ASCII
using a precision of 10, then output the
same number in binary using double
precision format.
Output:
3.14100
