Formatting Variables and Array Elements
The Variable Format (VF) command is used to format variables and array elements. The VF command is specified
by:
VF m.n
where m is the number of digits to the left of the decimal point (0 thru 10) and n is the number of digits to the
right of the decimal point (0 thru 4).
A negative sign for m specifies hexadecimal format. The default format for VF is VF 10.4
Hex values are returned preceded by a $ and in 2's complement.

Local Formatting of Variables
PF and VF commands are global format commands that affect the format of all relevant returned values and
variables. Variables may also be formatted locally. To format locally, use the command, {Fn.m} or {$n.m} following
the variable name and the ‘=’ symbol. F specifies decimal and $ specifies hexadecimal. n is the number of digits to
the left of the decimal, and m is the number of digits to the right of the decimal.

Converting to User Units
Variables and arithmetic operations make it easy to input data in desired user units such as inches or RPM.
