Fraction with a fraction in the denominator

Fraction with a fraction in the denominator

[Sander Maijers]

Hi,

How can I make the subfraction in the denominator of a fraction appear 
smaller even though the nominator is very small? This gives basically 
three equally long division lines:

\startfomula
	\frac{\mu_{Z}}{\frac{\sqrt{\VAR{Z}}{\sqrt{N_{\text{segments}}}}}
\stopformula

Sorry, I meant to write numerator. (In Dutch it is teller/noemer ;))

Hoi Sander,

The fraction line of a nested fractions is in fact shorter than that
of its parent fraction, but by a very small amout. This seems to be
the standard behaviour -- I tried the formula in LaTeX, and the
difference is just as small.

I agree with you that it would be nice if the difference were a bit
bigger in the case of continued fractions, but I suspect that would be
hard to automate. Anyway: below is a quick hack for manual adjustment.

(I've simplified your formula somewhat -- the one in your mail threw
some syntax errors to do with {} nesting, and the square roots made it
harder to make out the fraction line.)

Cheers,
Sietse

% Declare a new dimension variable
\newdimen\padwidth

% Set dimen
\padwidth=1em
% Define a command that adds a padwidth-sized kern
\define[0]\pad{\kern \padwidth}

% Needed for the formula
\def\VAR#1{\text{VAR}(#1)}

\startformula
    \frac{
        \mu_{Z}
    }{
        \pad\frac{
            \VAR{Z}
        }{
            N_{\text{segments}}
        }\pad
    }
\stopformula

ok, a new feature for SB:

\definemathfraction
   [wfrac]
   [margin=.25em]

\starttext

\startformula
     \wfrac {
         a
     } {
         \frac {
             b
         } {
             c
         }
     }
\stopformula

\stoptext

Thanks hans! Very nice feature. Wikified in
	http://wiki.contextgarden.net/Command/fraction
but the output on the wiki is not correct since ConTeXt there is mkii.

Best regards: OK
