Error description

  • When we invoke sprintf(buffer,"%.*f",4,f) to print 4
fractional digits, the result prints 5 digits.
This problem occurs when the program is compiled in
64-bit binary.

The problem happens on AIX6.1 TL07 SP03 and
AIX7.1 TL01 SP03.

Problem summary


    

  • In a 64-bit applications when we invoke
sprintf(buffer,"%.*f",4,f) to print 4 fractional digits, the
sprintf prints 5 digits, that is an extra digit, in the cases
where f is a floating point value in which integer part is
zero, as well as the fractional digits upto the specified
precision are all zeros. So essentially sprintf prints
an extra zero.

    



Problem conclusion


    

  • Code changes have been made to correct sprintf, to print
exact number of fractional digits as specified.
