How do I match all positive and negative numbers excluding 200.

I have tried the following and this regex works only for positive numbers but not for negative numbers.

^(?!(?:200)$)\d+

Expected result:

0
3
199
200 this is excluded
201 
-1  this should be a match
-10 this should be a match

0,3,199, and 201 match with the regex I tried

Any help is greatly appreciated.

One way of doing it if the numbers appear at the beginning of the lines:

^(?!200\b)-?\d+\b

DEMO

Explanation:
^ Should be start from the beginning of the line.
(?!200\b) 200 should not come next.
-? minus is optional.
\d+ the digit itself.
\b for word boundary. (The case @CarySwoveland mentioned in comment)
