==equation clarification== |
|||
The equation: |
|||
::* <big><math>state_{n + 1} \equiv 214013 \times state_n + 2531011 \pmod{2^{31}}</math></big> |
|||
should probably read |
|||
::* <big><math>state_{n + 1} \equiv [ 214013 \times state_n + 2531011 ] \pmod{2^{31}}</math></big> |
|||
to indicate that the modulus is for the entire equation, not just the last term; even though by inspection, it becomes obvious what was meant. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 23:33, 11 June 2015 (UTC) |
