It's obscure, yes, though the dictionary has this:

"Important! Changing the numberFormat does not automatically change the format of a number that's already in a container. It affects numbers only when they are calculated and then displayed or used as strings. Otherwise, the number retains its full numeric precision."

The "already in a container" should be more precise though and specify "in a variable". Fields are containers, but they only hold strings.

Thanks Jacque, a gold mine of information as usual. But it’s pretty obscure, 
isn’t it? All this started for me because I wanted to test if two numbers were 
equal, knowing that they probably weren’t exactly equal to the last decimal 
place but nevertheless were ‘engineering equal’ as it were - say to six places 
of decimals. So I tried to truncate them to that length and then compare them. 
More fool me. But now I think I know what should be done, thanks to you - and 
to everyone else who replied.

So really, if I want an uncomplicated string of characters derived
from a number via setting the numberFormat and then doing a
calculation, how do I get it?

You can turn it into a string by putting empty after it:

  put 1.55555 into tVar -- number
  set the numberformat to "0.00"
  add 1 to tVar -- still a number
  put tVar into fld 1 -- numberformat applied now, field contains a string 
"2.55"
  add 1 to tVar -- still a number, contains 3.55555
  put empty after tVar -- numberformat applies, tVar is a string
