Saluton!

Hello all,

I’m very interested in getting in contact with other rubyists who are

interested in numerical methods/scientific programming.

In particular I’m interesting in finding what’s currently available

in terms of math libraries.

Mathematical functions supported by Ruby 1.8’s Math library

```
acos, acosh, asin, asinh, atan, atan2, atanh, cos, cosh, erf,
erfc, exp, frexp, hypot, ldexp, log, log10, sin, sinh, sqrt, tan,
tanh
```

Additional functions provided by soon-to-be-released Extmath library

```
abs, acot, acoth, beta, ceil, cosec, cosech, cot, coth, exp10,
exp2, factorial, floor, gamma, gcd, lcm, ln_gamma, log2, pwr,
root, sec, sech, sign, sinc, sqr
```

Note that factorial, gcd and lcm operate on integer arguments.

I plan to release Extmath before weekend (on Rubyforge).

Gis,

Josef ‘Jupp’ Schugt
