to
other numeric types, and maximum and minimum constant values
for PosFloat
.

Float
, which isPosFloat(1.4E-45)
. - implicit macro def apply(value: Float): PosFloat
A factory method, implemented via a macro, that produces a
PosFloat
if passed a validFloat
literal, otherwise a compile time error.A factory method, implemented via a macro, that produces a
PosFloat
if passed a validFloat
literal, otherwise a compile time error.The macro that implements this method will inspect the specified
Float
expression at compile time. If the expression is a positiveFloat
literal, i.e., with a value greater than 0.0, it will return aPosFloat
representing that value. Otherwise, the passedFloat
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 inspectsFloat
literals at compile time, whereasfrom
inspectsFloat
values at run time.- value
the
Float
literal expression to inspect at compile time, and if positive, to return wrapped in aPosFloat
at run time.- returns
the specified, valid
Float
literal value wrapped in aPosFloat
. (If the specified expression is not a validFloat
literal, the invocation of this method will not compile.)

value.A factory method that produces an
Option[PosFloat]
given aFloat
value.This method will inspect the passed
Float
value and if it is a positiveFloat
, i.e., a value greater than 0.0, it will return aPosFloat
representing that value, wrapped in aSome
. Otherwise, the passedFloat
value is 0.0 or negative, so this method will returnNone
.This factory method differs from the
