In the last paragraph of my posting on preicision yesterday, I wrote

>   For -double-, 52 binary digits are assigned to the significand, 
>   and thus the largest integer-valued double not subject to rounding 
>   is (2^52)-1 =  4,503,599,627,370,495, which means 15.65 digits.


The paragraph should read, 

    For -double-, 52 binary digits are assigned to the significand, 
    and thus the largest integer-valued double not subject to rounding 
    is (2^53)-1 =  9,007,199,254,740,991, which means 15.95 digits.
