Missing value is equal to NANUM in Origin C. Although no constant name is defined for the missing value in LabTalk, the user can obtain it by using 0/0 in the script. For example:

nanum=0/0;
type Missing value is $(nanum);
//Should return
//Missing value is --

Note that missing value is evaluated as False in logical condition.
