PGAGetRealFromGrayCode(1)					      PGAPack						 PGAGetRealFromGrayCode(1)

NAME
       PGAGetRealFromGrayCode  -  interpets a binary reflected Gray code sequence in a binary string as encoding a real value and returns the real
       value it represents.

INPUT PARAMETERS
       ctx    - context variable
       p      - string index
       pop    - symbolic constant of the population the string is in
       start  - starting bit position in the binary representation
       end    - ending bit position in the binary representation
       lower  - lower bound of the interval the real number is defined on
       upper  - lower bound of the interval the real number is defined on

OUTPUT PARAMETERS
       none

SYNOPSIS
       #include "pgapack.h"
       double  PGAGetRealFromGrayCode(ctx, p, pop, start, end, lower, upper)
       PGAContext *ctx
       int p
       int pop
       int start
       int end
       double lower
       double upper

LOCATION
       evaluate.c

EXAMPLE
       Example:
       Decode a real value from the string p in population PGA_NEWPOP.	The
       value to decode lies on the interval [-10,20] and is represented
       using the 20 bits in bit positions 10--29.

       double x;
       :
       x = PGAGetRealFromGrayCode(ctx, p, PGA_NEWPOP, 10, 29, -10.0, 20.0);
