IBM FLOAT

The 4 byte float (8 bits per byte) is defined as: 
     byte1       byte2       byte3        byte4
   xxxx xxxx   xxxx xxxx   xxxx xxxx    xxxx xxxx
  |s|<=ex=>|   |<==============fr==============>|  
      (7)                     (24)
sign|exponent  |            fraction            |

    value =  (-1)^s  *  16^(ex-64) *  .fr 

             5E-79< value < 7E+75
