How to display number to two decimal places in bash function

Question

How should I take a number that is in hundreths of seconds and display it in seconds to two decimal places? Psuedo code to follow the dTime function I am not sure about but you\

Answer 1

"bc" and "dc" both truncate rather than round, so nowadays I prefer Perl

If "N" has your number of hundreths of seconds in it then:

$ perl -e "printf('%.2f', $N/100)"

I was never a Perl supporter but it is now ubiquitous and I have finally been swayed to using it instead of sed/awk etc.
