Printing formatted decimal numbers

I need to print formatted decimal numbers to a set number of decimal places.

Is there a way to do this with JavaScript ?

If not is there any existing/"library" functions to do this ?

Many thanks in advance,

Aaron

pi = 3.14159265;
x = n.toFixed(2);
// x == 3.14
y = n.toFixed(4);
// y == 3.1416

Note that this is only in JS1.5 and ECMAv3, but that is still most
everything released this century.

Also note that toFixed() is severely crippled in IE with it's bug. Read
the FAQ with regards to formatting a number with leading and/or trailing
zeroes.

Convert it to a string, pad it, print the string.
