Is one of a quantity expected to return the backing type?

[prittjam]

using Unitful
a = 1.0u"m"
one(eltype(a))

I would expect it to return one unit, but it just returns 1.0.

The current behavior is correct, since one returns the multiplicative identity element, i.e., x * one(x) == x.

[prittjam]

whats the best way to get the quantity one? e.g.,

one(eltype(x))*Unitful.unit(x[1])

[sostock]

oneunit(x) (or oneunit(eltype(x)), since it looks like you are operating on arrays)
