  12. I was told that C compiler automatically converts "float" variable
  13. internally to "double" for + - * / , etc operations. Is this true?
  14.  
  15. Can I force the C compiler not to do the conversion as I have an
  16. assignment on finding out various computing errors of different
  17. precisions? 
  18.  
  19. My advice from the lecturer is to have temporary variable of
  20. float to split a long equation to smaller step so that I can maximize
  21. the impact of single precision number on the evaluation. Is this
  22. feasible?
