Jak na matematiku a zlomky?

[Jaromír Kuben]

Dobry den.
S balikem amsmath mate k dispozici prikazy \dfrac a \tfrac, ktere 
vynucuji zlomky v displaymodu
resp. textmodu. Dalsi moznost, jak si vynutit displaymod, je 
$\displaystyle\frac ab$.
A konecne neco jako \everymath={\displaystyle} zpusobi, ze veskera 
matematika bude v displaymodu.
Musite ale zvazit, co je v displaymodu prijatelne, vseho moc skodi. 
Zalezi na konkretni situaci.
Zdravi
                 Jaromir Kuben
