Why not just use 'printf()' for this? Makes it somewhat less confusing
while doing essentially the same thing in the background:
printf "%05.02f\n", 4.5;
The difference lies in if the '$\' ($OUTPUT_RECORD_SEPERATOR) is set
when you use the first example it will add an extra newline that you
probably would not intend (given the \n in the format). printf() will
ignore the value of $\ and format only according to your format
argument.
Just a suggestion.
