Annunciators

Your HP-10C display contains five annunciators that tell you the status of the
calculator during certain operations. The annunciators are described, with the
operations they refer to, in the appropriate sections of this handbook.

Radix Mark and Digit Separator

A radix mark is the divider between the integer and fractional portions of a
number. A digit separator distinguishes the groups of digits in a large number.
In some countries the radix is a decimal point and the digit separator is a
comma, while in other countries the reverse is true. To interchange the radix
and digit separator conventions on your HP-10C, turn off the calculator, then
hold down the . key, turn the calculator back on, and release the . key
(./=).

Error Messages

If you attempt a calculation using an improper parameter, such as attempting to
find the square root of a negative number, an error message will appear in the
display. For a complete listing of error messages and their causes, refer to
