       A13 Floating point
           ______________
          There  are  two  possible  schemes  for  a  floating point
       package in BCPL:  on implementations where the cell  size  is
       big  enough  to hold the machine representation of a floating
       point number  the  Floating  Point  Language  Packet  may  be
       implemented and where this is not possible the Floating Point
       Procedure Packet may be  implemented.   In  either  case  the
       Floating Point I/O Procedures should be implemented.

          FPLUS(A,B,C)    C:=A#+B     resultis C
          FMINUS(A,B,C)   C:=A#-B     resultis C
          FNEG(A,B)       B:=#-A      resultis B
          FMULT(A,B,C)    C:=A#*B     resultis C
          FDIV(A,B,C)     C:=A#/B     resultis C
          FABS(A,B)       B:=#ABS A   resultis B
