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 between 1 and 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
