 * It seems a bit silly that >, < work but <= and >=, valid mathematical operators,
   result in an error.
 * Easy fix?

 * Hi,
 * thanks for your question, and sorry for the trouble.
 * Yes, this sounds like an easy fix, but unfortunately, it isn’t 🙁 The external
   PHP library that TablePress uses to parse formulas basically goes through the
   formulas one character at a time, on the look for operators, function names, 
   numbers, etc. That detection can however not take into account operators that
   are more than one character, from what I know.
 * I’d definitely like to add support for this in the future, but for now I can 
   only suggest to rewrite such expressions from
 *     ```
       a <= b
       ```
   
 * to the equivalent
 *     ```
       NOT( a > b )
       ```
   
 * or to do all the formula stuff in e.g. Excel and just import a CSV file with 
   the calculated results into TablePress.
 * Regards,
    Tobias
