Namespace/Module Path: Microsoft.FSharp.Collections.Set
Assembly: FSharp.Core (in FSharp.Core.dll)
// Signature: Set.isProperSubset : Set<'T> -> Set<'T> -> bool (requires comparison) // Usage: Set.isProperSubset set1 set2
The following code illustrates the use of the Set.isProperSubset function.
let set1 = Set.ofList [ 1 .. 6 ] let set2 = Set.ofList [ 1 .. 5 ] let set3 = Set.ofList [ 1 .. 6 ] let set4 = Set.ofList [ 5 .. 10 ] printfn "%A is a proper subset of %A: %b" set2 set1 (Set.isProperSubset set2 set1) printfn "%A is a proper subset of %A: %b" set3 set1 (Set.isProperSubset set3 set1) printfn "%A is a proper subset of %A: %b" set4 set1 (Set.isProperSubset set4 set1)
Output
set [1; 2; 3; 4; 5] is a proper subset of set [1; 2; 3; 4; 5; 6]: true set [1; 2; 3; 4; 5; 6] is a proper subset of set [1; 2; 3; 4; 5; 6]: false set [5; 6; 7; 8; 9; 10] is a proper subset of set [1; 2; 3; 4; 5; 6]: false
