Detailed Description

The type of the generated random value.

Constructs a default-initialized % subtract_with_carry_01 random number generator.

Constructs an explicitly seeded % subtract_with_carry_01 random number generator.

Parameters

__g	The seed generator function.

Seeds the initial state of the random number generator.

Seeds the initial state of the % subtract_with_carry_01 random number generator.

Gets the minimum value of the range of random floats returned by this generator.

Gets the maximum value of the range of random floats returned by this generator.

Gets the next random number in the sequence.

Parameters

__lhs	A % subtract_with_carry_01 random number generator object.
__rhs	Another % subtract_with_carry_01 random number generator object.

Returns

true if the two objects are equal, false otherwise.
