This .NET library offers useful extension methods to collections and specific types.

Extension methods for collections

• ArgMaxValue and ArgMinValue: Implementations of the known mathematics functions. They extend a collection of indices of value type I and take a function Func<I, V> mapping indices to values V, which must be comparable, i.e. implementing IComparable<V>. They return I? which is null if the collection is empty or the index where the value becomes maximum or minimum respectively.
• ArgMax and ArgMin: Same as above, except that type I is a reference type, thus the methods no longer need to return I?, they return I instead.
• RandomPickSequence: These overloads create an infinite collection from an array by picking elements randomly.
• CycleSequence: Creates an infinite collection by looping an array.

Extension methods for Double

• Squared: It squares the number.
• Powered: It raises the number to a power.

Extension methods for strings

• ComputePortableHashCode: Computes a string hash code which is guaranteed to be stable across AppDomain's, .NET framework versions and 32 or 64 bits flavors.

This library has no dependencies.
