Random number

Objetive

Create a class RandomNumber, with three static methods:

- GetFloat will return a number between 0 and 1 using the following algorithm:

seed = (seed * a + c) % m
result = abs(seed / m)

- GetInt(max) will return a number from 0 to max, using:
result = round(max * GetFloat)

- GetInt(min, max) will return a number from min to max (you must create this one totally on your own).

The starting values must be:
m = 233280;
a = 9301;
c = 49297;
seed = 1;

Code

Imports System
Namespace Random
    Class RandomNumber
        Private Shared m As Integer = 233280
        Private Shared a As Integer = 9301
        Private Shared c As Integer = 49297
        Private Shared seed As Integer = 1

        Public Shared Function GetFloat() As Single
            seed = (seed * a + c) Mod m
            Return Math.Abs(seed / m)
        End Function

        Public Shared Function GetInt(ByVal max As Integer) As Integer
            Return 0
        End Function

        Public Shared Function GetInt(ByVal min As Integer, ByVal max As Integer) As Integer
            Return 0
        End Function
    End Class
End Namespace
