I've inherited a Visual Studio/VB.Net numerical simulation project that has a likely inefficient calculation. Profiling indicates that the function is called a lot (1 million times plus) and spends about 50% of the overall calculation within this function. Here is the problematic portion

Result = (A * (E ^ C)) / (D ^ C * B) (where A-C are local double variables and D & E global double variables)

Result is then compared to a threshold which might have additional improvements as well, but I'll leave them another day

any thoughts or help would be appreciated
