Local fix

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.
