HP 33s Scientific Viewing a Variable without Recalling It, Reviewing Variables in the VAR Catalog

Viewing a Variable without Recalling It

The Šfunction shows you the contents of a variable without putting that number in the X–register. The display is labeled for the variable, such as:

) 

In Fraction–display mode ({‹), part of the integer may be dropped. This will be indicated by "…" at the left end of the integer.

To see the full mantissa, press . The integer part is the portion to the left of the radix ( ) or 8 ).

Šis most often used in programming, but it is useful anytime you want to view a variable's value without affecting the contents of t he stack.

where nn,nnn is the number of bytes of available memory. Pressing the {#} menu key displays the catalog of variables. Pressing the {} menu key displays the catalog of programs.

To review the values at any or all non–zero variables:

1.Press {Y{VAR}.

2.Press šor ™to move the list and display the desired variable. (Note the ©ª annunciators, indicating that the šand ™keys are active. If Fraction–display mode is active, cd indicator will not be turned on to indicate accuracy.)
