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.
