4. Calculations  
Precision  
The HP 6S scientific calculator calculates answers to 12-digit accuracy, but rounds answers  
to 10 digits in the display. When it performs a calculation using the result of a previous  
calculation, it uses the stored 12-digit value and not the 10-digit value displayed.  
Order of operations  
The HP 6S scientific calculator performs operations in the following order:  
º, Ê, Ä, Ã  
*, d  
+, -  
&
o, x, X

Perform calculations in the same way that you write them on paper.

Logical operations  
You can use the following logical operations to compare two numbers. When performing  
logical operations, keep the following points in mind:  
&o  
xX  
Ì
You cannot use decimal-base numbers in logical operations.  
The calculator compares the binary versions of the numbers you enter. If the number is  
less than 10 digits long, the calculator fills values to the left of the number with 0s—eg, if  
you compare hexadecimal F1 to octal 4, the calculator compares 0000010001 to  
0000000100.  
If you use one number with a logical operation, the calculator compares it to 0000000000.  
The logical operators work in the following way:  
1. The operation compares the binary digits in the corresponding positions in each of the  
numbers.  
2. The operation returns a binary digit corresponding to each position.  
3. If you are using a base other than binary, the result is shown in the base of the last  
number you entered.  
The following logical operators are available:
