OK, multiple dots, and any non-numeric characters discriminated as well:


Code:
sed -r '/[^0-9+.]/bW; /([.]).*\1/bW; /[1-9]/ {s/$/\tOK/; b}; :W; s/$/\tWRONG/' file
1       OK
1.5     OK
.5      OK
0.5     OK
+1      OK
.50     OK
0.5000  OK
+100    OK
+.5     OK
+1.3    OK
0.5a000 WRONG
+100b   WRONG
+.5;    WRONG
+z1.3   WRONG
-1      WRONG
-.5     WRONG
-1.3    WRONG
.0      WRONG
0.      WRONG
0.0     WRONG
+0      WRONG
+.0     WRONG
+0      WRONG
+0.0    WRONG
.0.5    WRONG
.1.1    WRONG
.1.3.5  WRONG


You could run the sedwith a "here-string" like
Code:
$ set -- .1.3.5
$ sed -r '/[^0-9+.]/bW; /([.]).*\1/bW; /[1-9]/ {s/$/\tOK/; b}; :W; s/$/\tWRONG/' <<< $1
.1.3.5    WRONG
