It sounds like you are expect base 10 logs & are using base e logs.
Remember Math.Log & Math.Exp are base e, not base 10. Its been too long to
remember the conversion, based on the "find the Inverse Log of a number"
thread in this newsgroup, the conversion appears to be:
log(x) / log(base)
and
exp(x * log(base))
In addition to Math.Log & Math.Exp, there are VB.Log & VB.Exp.
