[REBOL] Re: Math (division)

Hi Ammon
If you just want to know if it is a REBOL integer:
integer? x
If you want to know if a number has no digits after the decimal place (i.e.,
it is an integer in the mathematical sense), regardless of its REBOL type:
>> math-int: func [x [number!]][x // 1 = 0]
>> math-int pi
== false
>> x: to-decimal 2
== 2
>> type? x
== decimal!
>> math-int x
== true
>> type? 2 ** 52
== decimal!
>> math-int 2 ** 52
== true
>> math-int -2 ** 52
== true
