Re: Formatting numbers for output

Here is an example of what you could do:

Map[NumberForm[#,{4,2},NumberPadding->{"","0"}]&,Table[Random[],{10}]]

This generates a list of 10 random numbers in the range [0,1], and the {4,2} 
in NumberForm displays them as 4 digit reals with 2 digits to the right of 
the decimal point. The key trick is to use the option 
NumberPadding->{"","0"}.
