What is the expected behavior?

Calling Random.Double(double.MinValue, double.MaxValue) should generated a double between these constraints.

What is the actual behavior?

The method always returns Infinity.
This does not happen though when using e.g.

• double.MinValue, 0
• or 0, double.MaxValue.

A quick look at the Double method revealed that there is no magnitute/value limitation in line 186.
In particular, the calculation (max - min) + min causes this behavior.
Similar behavior can be reproduced for the Float and Decimal randomizers.

Please provide a stack trace.
