Concrete methods

def xmap[T, U](from: T => U, to: U => T)(c: Choose[T]): Choose[U]

Transform a Choose[T] to a Choose[U] where T and U are two isomorphic types whose relationship is described by the provided transformation functions. (exponential functor map)

Transform a Choose[T] to a Choose[U] where T and U are two isomorphic types whose relationship is described by the provided transformation functions. (exponential functor map)

implicit val chooseBigDecimal: Choose[BigDecimal]

Choose a BigDecimal number between two given numbers.

Choose a BigDecimal number between two given numbers.

The minimum scale used will be 34. That means that the fractional part will have at least 34 digits (more if one of the given numbers has a scale larger than 34).

The minimum scale was chosen based on Scala's default scale for expanding infinite fractions:

BigDecimal(1) / 3 // 0.3333333333333333333333333333333333

See chooseBigDecimalScale for more information about scale.
