apply(value: Double): NegDouble
A factory method, implemented via a macro, that produces a
NegDoubleif passed a validDoubleliteral, otherwise a compile time error.A factory method, implemented via a macro, that produces a
NegDoubleif 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 negativeDoubleliteral, it will return aNegDoublerepresenting that value. Otherwise, the passedDoubleexpression 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
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 negative, to return wrapped in aNegDoubleat run time.- returns
the specified, valid
Doubleliteral value wrapped in aNegDouble. (If the specified expression is not a validDoubleliteral, the invocation of this method will not compile.)

Doublevalue and if it is a negativeDouble, it will return aNegDoublerepresenting that value. Otherwise, the passedDoublevalue is not negative, so this method will throwAssertionError.This factory method differs from the

the specified

Passgiven a validDoublevalue, or an error value of typeEproduced by passing the given invalidIntvalue to the given functionf, wrapped in aFail.This method will inspect the passed

sumOf(first: NegDouble, second: NegZDouble, rest: NegZDouble*): NegDouble
Returns the
NegDoublesum of the passedNegDoublevaluefirst, theNegZDoublevaluesecond, and theNegZDoublevalues passed as varargsrest.Returns the
NegDoublesum of the passedNegDoublevaluefirst, theNegZDoublevaluesecond, and theNegZDoublevalues passed as varargsrest.This method will always succeed (not throw an exception) because adding a negative Double and one or more non-positive Doubles will always result in another negative Double value (though the result may be infinity).
This overloaded form of the
sumOfmethod can sum more than two values, but unlike its two-arg sibling, will entail boxing. -
def
sumOf(x: NegDouble, y: NegZDouble): NegDouble
Returns the
NegDoublesum of the passedNegDoublevaluexandNegZDoublevaluey.Returns the
NegDoublesum of the passedNegDoublevaluexandNegZDoublevaluey.This method will always succeed (not throw an exception) because adding a negative Double and non-positive Double will always result in another negative Double value (though the result may be infinity).
This overloaded form of the method is used when there are just two arguments so that boxing is avoided. The overloaded
sumOfthat takes a varargs ofNegZDoublestarting at the third parameter can sum more than two values, but will entail boxing and may therefore be less efficient. -

NegDouble, wrapped in aSuccess, given a validFloatvalue, or if the givenFloatis 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
ensuringValidcall will always succeed, you should use one of the other factory or validation methods provided on this object instead:isValid,tryingValid,passOrElse,goodOrElse, orrightOrElse.This method will inspect the passed
Floatvalue and if it is a negativeFloat, it will return aNegDoublerepresenting that value, wrapped in aSuccess. Otherwise, the passedFloatvalue is not negative, so this method will return anAssertionError, wrapped in aFailure.This factory method differs from the
applyfactory method in thatapplyis implemented via a macro that inspectsFloatliterals at compile time, whereas this method inspectsFloatvalues at run time.- value
the
Floatto inspect, and if negative, return wrapped in aSuccess(NegDouble).- returns
the specified
Floatvalue wrapped in aSuccess(NegDouble), if it is negative, else aFailure(AssertionError).
