→Sub-Formulae numbering with {{cmd|startsubformulas}}

== Sub-Formulae numbering with {{cmd|startsubformulas}} and {{cmd|startalign}} ==
To use subformula numbering, you can have to use {{cmd|startsubformulas}}/{{cmd|stopsubformulas}} and {{cmd|startalign}}. For example
Examples:
\definereferenceformat[eqref][left=(,right=)]
\startsubformulas[eq:total]
\startplaceformula[eq:first]placeformula\startformula c^2 = \startalign\NC a^2 + b^2 \stopformula\stopplaceformula NC = c^2 \startplaceformulaNR[eq:secondfirst]\startformula c^2 = NC a^2 + b^2 \stopformulaNC = c^2 \NR[eq:second]\stopplaceformulastopalign\stopformula
\stopsubformulas
Formula (\ineqref[eq:total]) states the Pythagora's Theorem twice,once in (\ineqref[eq:first]) and again in (\ineqref[eq:second]).
