  43. The AIX ksh is  a POSIX 1003.2 draft compliant (which draft?) shell. My
  44. documentation
  45. doesn't show the "-F" parameter for typeset and no indication for doing floating or
  46. fixed point arithmetic in the shell proper. You could look into using the "bc"
  47. utility 
  48. for what you need to do.
