signihcant digits to the right of the decimal point are shown, up to
12 digits.
fl Fix mode ( F i ; < ) —Displays numbers rounded to a specified number
of decimal places. Real numbers on the stack are displayed with
digit separators (separating digits into groups of three): commas (if
a period is used as the decimal point ) or periods (if a comma is used
as the decimal point).

digit to the left of the decimal point and a specified number of
decimal places) and an exponent.
