NIST Publishes Preview of Math Reference

An anonymous reader writes "Abramowitz & Stegun has been one of the most authoritative references for special functions and engineering mathematics since the 1960s, when it was published by the US Bureau of Standards (now NIST). NIST has been working on an freely-available online updated version to this legendary reference for years. A preview of the digital library of mathematical functions (which uses MathML and requires some of its fonts) is now available from NIST's website."

    The quadratic formula in LaTeX markup:

    x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
    The same in MathML:
