Higher Precision math

Some basic high-precision math functions This little program demonstrates the ability of VB to go beyond the built-in 16 digit level of precision. It demonstrates the computation of the sine, cosine, tangent, square root and cube root of an argument to a precision of up to 28 significant digits. In my work, I often encounter special situations where a higher level of precision is required, so I thought I'd share some of the basic routines I use to achieve it.
