MathML Test : mfrac

This test displays mfrac element with the attributes linethickness, numalign, denomalign and bevelled. The default values should respectively be 1, center, center and false.

1. check the default behavior with no attribute.
2. check for each attribute the behavior with non-default values.

• no attribute : $\frac{\text{numerator}}{\text{denominator}}$
• linethickness="0" : [$\genfrac{}{}{0ex}{}{\text{numerator}}{\text{denominator}}$ ]
• numalign="left" : $\frac{\text{num}\hfill }{\text{denominator}}$ ; numalign="right" :$\frac{\hfill \text{num}}{\text{denominator}}$
• denomalign="left" : $\frac{\text{numerator}}{\text{denom}\hfill }$ ; denomalign="right" :$\frac{\text{numerator}}{\hfill \text{denom}}$
• bevelled="true" : [$\raisebox{1ex}{$\text{numerator}$}\!\left/ \!\raisebox{-1ex}{$\text{denominator}$}\right.$ ]

Some test examples with several mfrac elements :

• $\raisebox{1ex}{$\frac{c-a}{b-a}$}\!\left/ \!\raisebox{-1ex}{$\frac{c-d}{b-d}$}\right.\in ℝ$
• $\left(\genfrac{}{}{0ex}{}{p}{n}\right)=\frac{n}{p}\left(\genfrac{}{}{0ex}{}{n-1}{p-1}\right)$
• $\frac{\frac{1}{2}+\frac{u}{3}}{x-y}$
