 Accuracy and Capacity
Output digits : Up to 10 digits.
Calculating digits : Up to 16 digits
In general, every reasonable calculation is displayed up to 10 digits
mantissa, or 10-digit mantissa plus 2-digit exponent up to 10 ± 99.
Numbers used as input must be within the range of the given
function as follows:
