PosDouble

A factory/assertion method that produces a PosDouble given a valid Double value, or throws AssertionError, if given an invalid Double value.

This method will inspect the passed Double value and if it is a positive Double, it will return a PosDouble representing that value. Otherwise, the passed Double value is not positive, so this method will throw AssertionError.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas from inspects Double values at run time. It differs from a vanilla assert or ensuring call in that you get something you didn't already have if the assertion succeeds: a type that promises a Double is positive.

A factory method that produces an Option[PosDouble] given a Double value.

This method will inspect the passed Double value and if it is a positive Double, it will return a PosDouble representing that value, wrapped in a Some. Otherwise, the passed Double value is not positive, so this method will return None.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas from inspects Double values at run time.

A factory method that produces a PosDouble given a Double value and a default PosDouble.

This method will inspect the passed Double value and if it is a positive Double, it will return a PosDouble representing that value. Otherwise, the passed Double value is positive, so this method will return the passed default value.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas from inspects Double values at run time.

A factory/validation method that produces a PosDouble, wrapped in a Good, given a valid Double value, or if the given Double is invalid, an error value of type B produced by passing the given invalid Double value to the given function f, wrapped in a Bad.

This method will inspect the passed Double value and if it is a positive Double, it will return a PosDouble representing that value, wrapped in a Good. Otherwise, the passed Double value is not positive, so this method will return a result of type B obtained by passing the invalid Double value to the given function f, wrapped in a Bad.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas this method inspects Double values at run time.

A predicate method that returns true if a given Double value is positive.

A validation method that produces a Pass given a valid Double value, or an error value of type E produced by passing the given invalid Int value to the given function f, wrapped in a Fail.

This method will inspect the passed Double value and if it is a positive Double, it will return a Pass. Otherwise, the passed Double value is positive, so this method will return a result of type E obtained by passing the invalid Double value to the given function f, wrapped in a Fail.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas this method inspects Double values at run time.

A factory/validation method that produces a PosDouble, wrapped in a Right, given a valid Double value, or if the given Double is invalid, an error value of type L produced by passing the given invalid Double value to the given function f, wrapped in a Left.

This method will inspect the passed Double value and if it is a positive Double, it will return a PosDouble representing that value, wrapped in a Right. Otherwise, the passed Double value is not positive, so this method will return a result of type L obtained by passing the invalid Double value to the given function f, wrapped in a Left.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Double literals at compile time, whereas this method inspects Double values at run time.

A factory/validation method that produces a PosDouble, wrapped in a Success, given a valid Float value, or if the given Float is invalid, an AssertionError, wrapped in a Failure.

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, or rightOrElse.

This method will inspect the passed Float value and if it is a positive Float, it will return a PosDouble representing that value, wrapped in a Success. Otherwise, the passed Float value is not positive, so this method will return an AssertionError, wrapped in a Failure.

This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Float literals at compile time, whereas this method inspects Float values at run time.

The largest value representable as a positive Double, which is PosDouble(1.7976931348623157E308).

The smallest positive value greater than 0.0d representable as a PosDouble, which is PosDouble(4.9E-324).

The smallest value representable as a positive Double, which is PosDouble(4.9E-324).

The positive infinity value, which is PosDouble.ensuringValid(Double.PositiveInfinity).

The formerly implicit posDoubleOrd field has been deprecated and will be removed in a future version of ScalaTest. Please use the ordering field instead.

A factory method, implemented via a macro, that produces a PosDouble if passed a valid Double 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 positive Double literal, it will return a PosDouble representing that value. Otherwise, the passed Double expression is either a literal that is not positive, 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 inspects Double literals at compile time, whereas from inspects Double values at run time.
