COMMENTS

This is the halting probability of a certain universal Chaitin (self-delimiting Turing) machine U.

The full (infinite precision) number is random and noncomputable.

The machine used is NOT universal, since each data bit is given in ASCII and contributes 7 bits to the program length. [From John Tromp, Mar 23 2009]
