precision
A number representing the number of digits to be printed for numbers printed with
the
print()
,
printbuffer()
, and

Details
This attribute specifies the precision (number of digits) for numeric data printed with the
print()
,
printbuffer()
, and
printnumber()
functions. The
format.asciiprecision
attribute is only
used with the ASCII format. The precision value must be a number from 0 to 16.
Note that the precision is the number of significant digits printed. There is always one digit to the left
of the decimal point; be sure to include this digit when setting the precision.
Example
format.asciiprecision = 10
x = 2.54
printnumber(x)
format.asciiprecision = 3
printnumber(x)
Output:
2.54000
2.54e+00
