BigFractionFormat()
Create an improper formatting instance with the default number format
for the numerator and denominator.
|
BigFractionFormat(NumberFormat format)
Create an improper formatting instance with a custom number format for
both the numerator and denominator.
|
BigFractionFormat(NumberFormat numeratorFormat,
NumberFormat denominatorFormat)
Create an improper formatting instance with a custom number format for
the numerator and a custom number format for the denominator.
