Radix Mark and Digit Separator
A radix mark is the divider between
the integer and fractional portions of
a number. A digit separator dis- [)/[oN]
tinguishes the groups of digits in a
large number. In some countries the ) o
radix is a decimal point and the digit Radix Mark/Digit
separator is a comma, while in other Separator Exchange
countries, the reverse is true. To
change the radix/digit separator
convention on your HP-11C, turn off the calculator, then hold down
the (-] key, turn the calculator back on, and release the [-] key
([:]/[oN)).
