k Calculation Ranges, Number of Digits,

and Precision

The calculation range, number of digits used for internal

calculation, and calculation precision depends on the type

of calculation you are performing.

Number of Digits for 15 digits

Internal Calculation

Precision

In general,  1 at the 10th digit

for a single calculation. Precision

for exponential display is  1 at

the least significant digit. Errors

are cumulative in the case of

consecutive calculations.
