TRandomDouble

• Its constructor establishes a seed value for the first random value. When passed a seed value in the range of the generator, the constructor uses it. When passed an out of range seed, the constructor throws a TRandomException. When no seed value is passed, the constructor generates one randomly.
• Next returns the next random number in the sequence.
• GetHighestRandom and GetLowestRandom return the upper and lower limits, respectively, of the range of the generator.
