How to set numeric value in environment variable

Question

Problem: I want to set a counter variable (a numeric value) in environment variable, so in "Test" we can control the flow.

My experiment: I wrote a simple API call with following-

1. Prescript sets the counter variable-

   postman.setEnvironmentVariable("mycounter", 1);
   

2. Test verifies the counter variable, if its value equals to 1, increment it by one-

   if (postman.getEnvironmentVariable("mycounter") == 1 ) {
   
       postman.setEnvironmentVariable("result", "YES");       
       postman.setEnvironmentVariable("mycounter", 
           1+postman.getEnvironmentVariable("mycounter")); 
   } 
   else {
       postman.setEnvironmentVariable("result", "NO"); 
   }
   

But when i check the value for "mycounter"-

• Actual value: 11
• Expected value: 2

Can anybody point out how to set numeric value in environment variable?

I got workaround. By using Number function convert string to integer.

So

if (postman.getEnvironmentVariable("mycounter") == 1 ) {
    postman.setEnvironmentVariable("result", "YES");
    postman.setEnvironmentVariable("mycounter", 1+Number(postman.getEnvironmentVariable("mycounter")));  
} else {
    postman.setEnvironmentVariable("result", "NO"); 
}
