- final val MaxValue: PosDouble
The largest value representable as a positive
Double
, which isPosDouble(1.7976931348623157E308)

The smallest value representable as a positive
Double
, which isPosDouble(4.9E-324)
. - implicit macro def apply(value: Double): PosDouble
A factory method, implemented via a macro, that produces a
PosDouble
if passed a validDouble
literal, otherwise a compile time error.A factory method, implemented via a macro, that produces a
PosDouble
if passed a validDouble
literal, otherwise a compile time error.The macro that implements this method will inspect the specified
Double
expression at compile time. If the expression is a positiveDouble
literal, i.e., with a value greater than 0.0, it will return aPosDouble
representing that value. Otherwise, the passedDouble
expression 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
from
factory method in that this method is implemented via a macro that inspectsDouble
literals at compile time, whereasfrom
inspectsDouble
values at run time.- value
the
Double
literal expression to inspect at compile time, and if positive, to return wrapped in aPosDouble
at run time.- returns
the specified, valid
Double
literal value wrapped in aPosDouble
. (If the specified expression is not a validDouble
literal, the invocation of this method will not compile.)

value.A factory method that produces an
Option[PosDouble]
given aDouble
value.This method will inspect the passed
Double
value and if it is a positiveDouble
, i.e., a value greater than 0.0, it will return aPosDouble
representing that value, wrapped in aSome

value is 0.0 or negative, so this method will returnNone
