The companion object for PosDouble that offers
factory methods that produce PosDoubles,
implicit widening conversions from PosDouble to
other numeric types, and maximum and minimum constant values
for PosDouble.

def
apply(value: Double): PosDouble
A factory method, implemented via a macro, that produces a
PosDoubleif passed a validDoubleliteral, otherwise a compile time error.A factory method, implemented via a macro, that produces a
PosDoubleif passed a validDoubleliteral, otherwise a compile time error.The macro that implements this method will inspect the specified
Doubleexpression at compile time. If the expression is a positiveDoubleliteral, i.e., with a value greater than 0.0, it will return aPosDoublerepresenting that value. Otherwise, the passedDoubleexpression is either a literal that is 0.0 or negative, or is not a literal, so this method will give a compiler error.This factory method differs from the
fromfactory method in that this method is implemented via a macro that inspectsDoubleliterals at compile time, whereasfrominspectsDoublevalues at run time.- value
the
Doubleliteral expression to inspect at compile time, and if positive, to return wrapped in aPosDoubleat run time.- returns
the specified, valid
Doubleliteral value wrapped in aPosDouble. (If the specified expression is not a validDoubleliteral, the invocation of this method will not compile.)

A factory method that produces an

Option[PosDouble]given aDoublevalue.This method will inspect the passed
Doublevalue and if it is a positiveDouble, i.e., a value greater than 0.0, it will return aPosDoublerepresenting that value, wrapped in aSome. Otherwise, the passedDoublevalue is 0.0 or negative, so this method will returnNone.This factory method differs from the
applyfactory method in thatapplyis implemented via a macro that inspectsDoubleliterals at compile time, whereasfrominspectsDoublevalues at run time.- value
the
Doubleto inspect, and if positive, return wrapped in aSome[PosDouble].- returns
the specified
Doublevalue wrapped in aSome[PosDouble], if it is positive, elseNone.
