No

In the documentation for the DATATYPE bif, for the 'W' (whole) option:

... while 13E+1 is not a whole number...

All version of REGINA (and other REXXes) return 1
(indicating that it IS a whole number).

I don't agree with the statment that "... it must be interpreted as 130 plus/minus 5."

Also, nowhere is a NUMBER defined (let alone, what is a valid REXX number).

The statement: A string is a valid REXX number if DATATYPE returns NUM
isn't a concisei definition. It is what it is. It'll get fixed when it gets fixed.
It ain't over until it's over. A number is any valid REXX number.

Also, several places in the Regina doc mention something to the effect:

... according to NUMERIC.

Probably, it should say: ... according to NUMERIC DIGITS.

    How is it that just anyone can write a weblog and get as popular as this? Its not like youve said anything incredibly impressive Cmore like youve painted a pretty picture around an issue that you know nothing about! I dont want to sound mean, right here. But do you genuinely think that you can get away with adding some pretty pictures and not genuinely say anything?
