Bug: Comparison of zero to uninitialized variable returns true, and handling of long integers

[bertysentry]

The below script Awk prints "wrong":

// { a = 0 ; if (a == "") { print "wrong" } else { print "right" } }

Also, integer numbers greater than 2^31 are treated as Double, and output with a pseudo-scientific notation (3.45789E+9), which is not the behavior of the "official" awk.

I will shoot another PR for this. Thanks!

Hmm. Interesting. What do you regard as the official AWK?

Good question! ;-) What I consider as one official AWK, is GNU AWK: https://www.gnu.org/software/gawk/manual/html_node/Strings-And-Numbers.html

But I don't want to enter a political debate over AWK :-D

I agree. Gawk is well done. It is a proper superset of the Bell Labs version and the convenience functions that they added.

I would like to eventually see Jawk with those same extensions as long as the core Bell Labs compliant, if I can use that as a standard.
