 How to force precision in SAGE? jaydfox Long Time Fellow Posts: 440 Threads: 31 Joined: Aug 2007 08/18/2007, 11:06 PM Never mind, I figured it out. Apperently, e^z and exp(z) are not equivalent. The former uses double precision, as if it were doing the following internally: $e^z = \frac{e^z}{ln(b)}$, with b = 2.7182818284590458..., where that final 8 should be a 2. In other words, it treats e as any other base, and solves e^z by performing exp(z)/ln(e), where e is only accurate to double precision. Now I know not to use e^z. ~ Jay Daniel Fox « Next Oldest | Next Newest »
