title: Using regular expressions to validate a numeric range
body: <p>My input number is an int. But the input number must be in a range from -2055 to 2055 and I want to check this by using regular expression.</p>
  
  <p>So is there anyway to write a regular expression to check whether a number is in (-2055, 2055) or not ?</p>
  
  <p>It is easier to use if statement to check whether the number is in range or not. But I'm writing an interpreter so I should use regex to check the input number</p>
