Hello I am trying to print the output of a number as follows:

printf("%8.2e\n",0.000123);

This gives me the output in my 32 bit widnows xp as:

1.23e-004

The problem is there are 9 characters in the output instead of 8. So, how can I control the number of digits on the exponent so that it prints e-4 or e-04 rather than e-004?
