This code was not tested and breaks in Release builds, reverting to restore
functionality of the nightly. All in-game menus do not work and generating
a world crashes.
This reverts commit a9be52c41a.

Random Math::rand = Random();

|
//Returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0.
|
|
//Returned values are chosen pseudorandomly with (approximately) uniform distribution from that range.
|
|
//When this method is first called, it creates a single new pseudorandom-number generator, exactly as if by the expression
|
|
//
|
|
//new java.util.Random
|
|
//This new pseudorandom-number generator is used thereafter for all calls to this method and is used nowhere else.
|
|
//This method is properly synchronized to allow correct use by more than one thread. However, if many threads need to
|
|
//generate pseudorandom numbers at a great rate, it may reduce contention for each thread to have its own pseudorandom-number generator.
|
|
//
|
|
//Returns:
|
|
//a pseudorandom double greater than or equal to 0.0 and less than 1.0.

//Returns the closest long to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result,
|
|
//and casting the result to type long. In other words, the result is equal to the value of the expression:
|
|
//(long)Math.floor(a + 0.5d)
|
|
//Special cases:
|
|
//
|
|
//If the argument is NaN, the result is 0.
|
|
//If the argument is negative infinity or any value less than or equal to the value of Long.MIN_VALUE, the result is equal to the
|
|
//value of Long.MIN_VALUE.
|
|
//If the argument is positive infinity or any value greater than or equal to the value of Long.MAX_VALUE, the result is equal to the
|
|
//value of Long.MAX_VALUE.
|
|
//Parameters:
|
|
//a - a floating-point value to be rounded to a long.
|
|
//Returns:
|
|
//the value of the argument rounded to the nearest long value.
