A factory method, implemented via a macro, that produces a
PosZFloat
if passed a valid Float
literal, otherwise a compile time error.
A factory method, implemented via a macro, that produces a
PosZFloat
if passed a valid Float
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 non-negative Float
literal,
it will return a PosZFloat
representing that value.
Otherwise, the passed Float
expression is either a literal
that is not non-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 inspects Float
literals at compile
time, whereas from
inspects Float
values at run time.

specified expression is not a valid Float
literal, the invocation of this method will not
compile.)
A factory/assertion method that produces a PosZFloat

,
if given an invalid Float
value.
A factory/assertion method that produces a PosZFloat
given a
valid Float
value, or throws AssertionError
,
if given an invalid Float
value.
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 non-negative Float
, it will return a PosZFloat
representing that value.
Otherwise, the passed Float
value is not non-negative, 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 Float
literals at
compile time, whereas from
inspects
Float
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 Float
is positive.

A factory method that produces an Option[PosZFloat]

This method will inspect the passed Float

This method will always succeed (not throw an exception) because adding a non-negative Float to another non-negative Float will always result in another non-negative Float value (though the result may be infinity).
This overloaded form of the sumOf
method can sum more than two
values, but unlike its two-arg sibling, will entail boxing.

Returns the PosZFloat
sum of the passed PosZFloat

This method will always succeed (not throw an exception) because adding a non-negative Float to another non-negative Float will always result in another PosZFloat Float 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 sumOf
that takes a varargs of
PosZFloat
starting at the third parameter can sum more than two
values, but will entail boxing and may therefore be less efficient.
