Formatted output

[David M Goblirsch]

Has anyone already developed a library of Haskell functions for
formatted output?  I'm interested in something like

        formatFloat :: (Int,Int) -> Float -> String

        formatFloat (w,d) x

where w is the width of the field and d is the number of digits to use
after the decimal point, i.e., formatFloat is like C's %w.df specifier.
Thus

        formatFloat (10,4) 3.1415926535

would evaluate to "    3.1416".

Thanks.
