The default multiplier is a period:

NumberForm[12345678.9,10]

Use a comma instead:

NumberForm[12345678.9,10,NumberPoint->","]

Interpret numbers with a custom decimal point:

Interpreter["Number",NumberPoint->"@"]["2@3"]

OpenersExampleSection1(Spacer1)Scope  (2)

Use (RefLink[NumberPoint, paclet:ref/NumberPoint]) with (RefLink[PaddedForm, paclet:ref/PaddedForm]):

PaddedForm[12345678.9,10,NumberPoint->","]

(RefLink[EngineeringForm, paclet:ref/EngineeringForm]):

EngineeringForm[12345678.9,10,NumberPoint->","]

(RefLink[ScientificForm, paclet:ref/ScientificForm]):

ScientificForm[12345678.9,10,NumberPoint->","]

(RefLink[AccountingForm, paclet:ref/AccountingForm]):

AccountingForm[12345678.9,10,NumberPoint->","]

Use any string as a number point:

NumberForm[12345678.9,10,NumberPoint->" my number point "]
