❔ Why is PointF not simply Point<float>?

Why isn't there simply a generic `Point` class that allows for `Point `, ...? Is it for historical or performance reasons?

Why isn't there simply a generic

Point

Point

Point

Point class that allows for

Point<int

Point<int

Point<int

Point<int,

Point<float

Point<float

Point<float

Point<float,

Point<decimal>

Point<decimal>

Point<decimal>

Point<decimal>, ...?

this would only be possible in .net 7 and up

and since that only came out last year, yeah, it's for historical reasons

Why is that?

ero•2/21/23, 10:14 PM

because you need to constrain the generic parameter to something that is a number

ero•2/21/23, 10:14 PM

and .net 7 introduced generic math with INumber<T>INumber<T>

ero•2/21/23, 10:15 PM

so you could technically have struct Point<TNumber> where TNumber : INumber<TNumber>struct Point<TNumber> where TNumber : INumber<TNumber>

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
