In the articles above, I put an emphasis on random variate generation that:

• Samples exactly from a discrete distribution (such as Bernoulli factory algorithms).
• Samples from a continuous distribution with arbitrary precision and a user-specified accuracy.
• Avoids floating-point arithmetic.
• Avoids calculating transcendental functions when possible.

Colors, Graphics, and Music
