Compares two pseudo-random number engines. Two engines are equal, if their internal states are equivalent, that is, if they would generate equivalent values for any number of calls of operator().

Parameters

lhs, rhs

-

engines to compare

Return value

1) true if the engines are equivalent, false otherwise.

2) true if the engines are not equivalent, false otherwise.

Exceptions

(none)
