  Calculation Ranges, Number of Digits, 
and Precision
  The calculation range, number of digits used for internal calculation, and 
calculation precision depend on the type of calculation you are performing. 
  
  Calculation Range and Precision 
 Calculation Range 
  ±  1  ×  10 
–99 
 to  ± 9.999999999  ×  10 
99 
 or 0 
 Number of Digits for Internal 
Calculation 
 15 digits 
 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.
