Can someone tell me whether I can express $$a ≈ 922\text{ trillion}, a > 922\text{ trillion}, a = 922,337,203,685,477.5808$$ using the following notation:
Possible way to abbreviate notation for relations operating on the same LHS
in a mathematical text?
If I can't, can someone tell me an abbreviating notation similar to this notation, that can be used?
Background
I'm asking these questions in relation to simplifying mathematical expressions on the new Data type summary page for the VBA programming language. In particular, various ranges are specified for different data types, and I want to improve general readability of these ranges, especially in regard to comparing the ranges.
The reader may want to simply read a ball-park upper-limit figure for a range, which is why '922 trillion' is in the text. It is easier to read than the precise upper limit, & this may be all that a reader is interested in. At the same time, some readers may want to know the exact upper limit.
I'm not so concerned about readers not being able to straightaway read any notation that I use, as I'm considering hyperlinking to verbose English-language interpretations for each of the mathematical texts on the page.
