Hello, Could someone be so kind to tell me why I cannot set Times as math font? The line \definetypeface [myFont] [mm] [math,boldmath] [myfont] [default] [encoding=t2a] seems to do nothing; other code works well. \loadmapfile[t2a-monotype-timesttf.map] \usetypescriptfile[type-buy] \usetypescript[serif][fallback] \starttypescript [serif] [myfont] [t2a] \definefontsynonym [Serif] [t2a-TINRPSMT] [encoding=t2a] \definefontsynonym [SerifBold] [t2a-TINRPSBM] [encoding=t2a] \definefontsynonym [SerifItalic] [t2a-TINRPSIM] [encoding=t2a] \definefontsynonym [SerifBoldItalic] [t2a-TINRPSBI] [encoding=t2a] \stoptypescript \definetypeface [myFont] [rm] [serif] [myfont] [default] [encoding=t2a] \definetypeface [myFont] [mm] [math,boldmath] [myfont] [default] [encoding=t2a] \definetypeface [myFont] [tt] [mono] [typewriter][default][encoding=t2a] \setupbodyfont[myFont,12pt] \starttext Uniform distribution (over an interval) means that every number from that interval is equally probable.
