{
int rval = 0;
if (fontarea[f] == OTGR_FONT_FLAG) {
XeTeXFontInst* font = (XeTeXFontInst*)getFont((XeTeXLayoutEngine)fontlayoutengine[f]);

{
int rval = 0;
if (fontarea[f] == OTGR_FONT_FLAG) {
XeTeXFontInst* font = (XeTeXFontInst*)getFont((XeTeXLayoutEngine)fontlayoutengine[f]);
rval = getMathConstant(font, (mathConstantIndex)n);
/* scale according to font size, except the ones that are percentages */
if (n > scriptScriptPercentScaleDown && n < radicalDegreeBottomRaisePercent)
