Well, to old guys like me, 9E707 is programming language jargon,
not scientific notation, but I know what you mean.
string is a number
------------- ----------------
9E707 true
1.4 * 10^3 false
10,000 false
1.000 true
IX false
2222222222222 true
10 true
$101.50 false
++0 true
expression = expression -->
------------- --------------- ---------------
"9E707" "9E707" false
.2 + .2 + .2 + .2 + .2 10 false
1.00000000000001 + 0 1 false
1.000000000000001 + 0 1 true
1.000000000000005 + 0 1 false
"-0" "+0" true
put .000000000001 & "X" --> .00000000001X
put 1.000000000001 & "X" --> 1.00000000001X
put 2^(1/2) & "X" --> 1.414214X
put 100000000000000000000001 + 0 --> 99999999999999991611392
