PROGRAM:
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.
SYNOPSIS

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);
