I'm not sure since the formula's png file is displayed as black text on almost-black background... #-)

Take a look at the implementation suggested in "Numerical Recipes in C", section 6.4. The respective pages are freely available online in PDF format. However, you still need a Gamma or lnGamma function... or a another way of calculating B(a,b) where a and b may be half-integers. ;-)
