  14. I want a function which will evaluate a string of numbers and
  15. arithmetic operators. That is, whwn I call
  16.   
  17. eval_func(2*5)
  18.  
  19.  a value of 10 will be returned.
  20.  
  21. Ideally, I'd like the code to be able to handle several operators
  22. in the string, so that
  23.  
  24. eval_func((3*5.7)/(2-.77)+4.5)
  25.  
  26. will be evaluated just as easily.
  27.  
  28. All suggestions gratefully appreciated..
