Command Usage Tips
• The commands included in the Reg sub-menu can take a long
time to execute in logarithmic, e exponential, ab exponential, or
power regression calculation when there are a large number of
data samples.

Calculations
(BASE-N)
The BASE-N Mode lets you perform arithmetic calculations, negative
value calculations, and logical operations with binary, octal, decimal,
and hexadecimal values.
All calculations in this section are performed in the BASE-N
Mode (N4).
