Thanks Michael,

That's a nice function.  I learned alot going through the code.  
I did find one functional bug \fmtnum[decplaces=-1]{1.2670E+5} returns 10.  
Seems to me if the exponent is larger than the number of decimal places in the input the error occurs. 
\fmtnum[decplaces=-1]{1.2670E+4} works fine.

Something I'd be interested in is \fmtnum{arbitrary format number} --> chosen output format of #.# or or #.#E# or #.#x10^{#}
This is the only functionality which is absent from every number format package including siunitx.
