Re[2]: How to calculate STDev?

As for TS7, someone needs to perform an independent test to make sure that their
TS7 double precision is in fact double precision.

For the rest of their products, you can perform SD with single-precision, but it
depends on how you are using SD.  Given the rage for tick data these
days, and since computers are getting more powerful for less, I can see people
writing code that requires more iterations, which further corrupts the
final result if the whole process is limited by single precision.
