Inputting Values

In the BASE-N Mode, you can input values using the currently selected number base.

•A Syntax ERROR occurs if you input values that are not allowed for the currently selected number base (such as inputting 2 while binary is selected).

•You cannot input fractional values or exponential values in the BASE-N Mode. If a calculation produces a fractional value, the decimal part is cut off.
