VF (Variable Format)
[General]
DESCRIPTION:
The VF command allows the variables and arrays to be formatted for number of digits before and after the
decimal point. When displayed, the value m represents the number of digits before the decimal point, and
the value n represents the number of digits after the decimal point. When in hexadecimal, the string will be
preceded by a $. Hex numbers are displayed as 2's complement with the first bit used to signify the sign.
If a number exceeds the format, the number will be displayed as the maximum possible positive or negative
number (i.e. 999.99, -999, $8000 or $7FF).

m and n are unsigned numbers. A negative m specifies hexadecimal format.
