Numerical evaluation of modified Bessel equation

[Morberticus]

Not sure if this is the right place. Mathematica has a function BesselK[0,x] that returns the value of the modified Bessel function K_0 at x. Is there public documentation of how this algorithm works? If not, is there documentation regarding any algorithm of K_0? I am hoping it doesn't involve one of the integral expressions. The argument ,x, in my case is real.

Thanks
