  Sure, I know, but how do they say numbers?  Working with the blind ham made me sensitive to things I wouldn't normally be aware of.  7150 is either "seven one five zero" or  "Seven thousand one hundred fifty"   
In current radios it's "seven point one five zero zero zero zero" ..Huh?

We don't talk that way.  The Double talk has a digit mode and a "number mode".  I put it in that number mode, but break up the command strings so it talks more goodly-better. (;-).
14.253  "Fourteen point two fifty three"

Then there's  14.253.55  "fourteen point two fifty three dot fifty five"  I thought using different words for the two decimals would improve intelligibility as well.

You know that sea of entropy we were going to drown in?  Well, upon closer examination, it turned out to be ignorance.  S. Noskowicz 1987
