Fraction bar not extending in linear/skewed fractions #148

Open bwiernik opened 5 years ago

bwiernik commented 5 years ago

In Word 2019, the solidus extends to a long horizontal bar for stacked fractions, but it remains a normal-sized solidus when stacked or linear fraction formats are specified (i.e., if a division slash [U+2215] or a fraction slash [U+2044] are used).

(r_gG r_obs)/√(p(1-p)(1-r_gG^2 ) )

(r_gG r_obs)⁄√(p(1-p)(1-r_gG^2 ) )

〖r_gG r_obs〗∕√(p(1-p)(1-r_gG^2 ) )

(r_gG r_obs)⊘√(p(1-p)(1-r_gG^2 ) )

Have you tested this behaviour with the Camria Math font? I am trying to understand whether this is a font or math handler issue.

bwiernik commented 3 years ago

They extend as expected with Cambria Math

Thanks. Will have to go and remind myself how we implemented this feature in Cambria Math.

bwiernik commented 3 years ago

Cool. Did not realize you were involved in the development of Cambria Math. Very cool!

Have added growing forms of the fraction slash in dev for 2.20 image
