A factory method, implemented via a macro, that produces a
NegDouble
if passed a validDouble
literal, otherwise a compile time error.A factory method, implemented via a macro, that produces a
NegDouble
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 negativeDouble
literal, it will return aNegDouble
representing that value. Otherwise, the passedDouble
expression is either a literal that is not 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 negative, to return wrapped in aNegDouble
at run time.- returns
the specified, valid
Double
literal value wrapped in aNegDouble
. (If the specified expression is not a validDouble
literal, the invocation of this method will not compile.)

value, or if the givenFloat
is invalid, anAssertionError
, wrapped in aFailure
.Note: you should use this method only when you are convinced that it will always succeed, i.e., never throw an exception. It is good practice to add a comment near the invocation of this method indicating why you think it will always succeed to document your reasoning. If you are not sure an
ensuringValid
call will always succeed, you should use one of the other factory or validation methods provided on this object instead:isValid
,tryingValid
,passOrElse
,goodOrElse
, orrightOrElse

Float
value and if it is a negativeFloat
, it will return aNegDouble
representing that value, wrapped in aSuccess
