YOUR WP 34S IN VARIOUS OPERATING MODES

The Display

The LCD is your window to your WP 34S – there you see what is going on and what the
results are. This display sports a total of 400 elements in three sections: numeric, dot
matrix and fixed symbols. The numeric section features a minus sign and 12 digits for the
mantissa, as well as a minus sign and 3 digits for the exponent. The dot matrix is 6 dots
high and 43 dots wide, allowing for some 7 to 12 characters, depending on their widths.
The fixed symbols on the top right side (except the big '=') are called annunciators.
The ten annunciators are for indicating modes.
The numeric section in the lower part of the LCD is used for displaying numbers in
different formats, status data, or message parts. See the examples below for more.
The dot matrix section above is used for passing additional information to the user.
During command input, for example, the dot matrix displays the command chosen
until input is completed, i.e. until all required trailing parameters are entered. The
