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.

Base-nCalculations

(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).
