[luatex] Question about tex.setmath(..., ..., ...) [hope this is the right list]

[Akira Kakuto]

Dear Graham,

Sorry I was wrong.

\directlua{
tex.setmath("global", "fractionnumup", "display", 131072)
tex.setmath("global", "fractionnumvgap", "display", 163840)
}

seems not to change spacing, as you pointed out.

Best,
Akira
