Topic: Two equal Real Variables are showing as not equal

[mbrandt5]

Hey all,

I am getting a pretty weird glitch on an autolisp command I am working on here. 
I have two variables that are both listed as reals, and the watch is clearly showing that they are both equal.
Though with I compare them it is showing them as not equal. 
I have attached an image depicting the watch list error, and listed below what the watch list is showing.
Any idea how or why this could occur?

Watch list:
(CADR BPT21) = 261.994
(CADR VBOP1A) = 261.994
(= (CADR VBOP1A) (CADR BPT21)) = NIL

The watch window truncates the decmial places
Try "equal" instead of "=" with a fuzz
The fuzz is a real number defining the maximum amount by which expr1 and expr2 can differ and still be considered equal.

(equal (CADR VBOP1A) (CADR BPT21) 0.001)

Cheers, Rod.
