Hi all,

I've been looking through the docs for a way to print decimals to a defined 
precision.

I can get close to what I want using something like ~a and giving it a set 
width without having to build a function to do so. I mean I can build a 
function to do as its just a bit of string manip but it feels really odd 
that there doesn't seem to be a built in way to do so even though we try to 
keep all the decimals in fractional notation to maintain precision as long 
as possible in racket.

any ideas anyone or am I just being blind and its right there in the docs 
somewhere?

thanks,
Scott
