Choose

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.

Choose a java.math.BigDecimal number between two given numbers.

ZoneOffset values have some unusual semantics when it comes to ordering. The short explanation is that (ZoneOffset.MAX < ZoneOffset.MIN) == true. This is because for any given LocalDateTime, that time applied to ZoneOffset.MAX will be an older moment in time than that same LocalDateTime applied to ZoneOffset.MIN.

From the JavaDoc,

"The offsets are compared in the order that they occur for the same time of day around the world. Thus, an offset of +10:00 comes before an offset of +09:00 and so on down to -18:00."

This has the following implication,

 scala> ZoneOffset.MIN
val res0: java.time.ZoneOffset = -18:00

scala> ZoneOffset.MAX
val res1: java.time.ZoneOffset = +18:00

scala> ZoneOffset.MIN.compareTo(ZoneOffset.MAX)
val res3: Int = 129600

This implementation is consistent with that comparison.
