Hi,

I want to format an integer as hours and minutes.

Of course it’s easy to write this myself, but let’s respect DRY!

Is there a method I can use so that integers are converted to strings of  
2 digits?

So:  
2 --\> 02  
11 --\> 11  
4 --\> 04

thanks!

Yep, you can use sprintf:

> > sprintf(“%0.2d”, 4)  
> > =\> “04”
