Fraction bar not extending in linear/skewed fractions #148

Open bwiernik opened 4 years ago

bwiernik commented 4 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

This makes me so excited!
