NAME

       PGAEncodeRealAsGrayCode - encodes a real value as a binary reflected Gray code sequence

INPUT PARAMETERS

       ctx    - context variable
       p      - string index
       pop    - symbolic constant of the population the string is in
       start  - starting bit position in p to encode val in
       end    - ending bit position in p to encode val in
       low    - lower bound of the interval the val is defined on
       high   - lower bound of the interval the val is defined on
       val    - the real number to be represented as a binary string

OUTPUT PARAMETERS

       side   -effect.

EXAMPLE

       Encode 3.14 from the interval [0,10] in 30 bits in bit positions
       0--29 in string p in population PGA_NEWPOP as a binary reflected Gray
       code sequence.

       PGAContext *ctx;
       int p;
       :
       PGAEncodeRealAsGrayCode(ctx, p, PGA_NEWPOP, 0, 29, 0.0, 10.0, 3.14);
