Interpets a binary reflected gray code sequence in a binary string as encoding a real value and returns the real value it represents.
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
none

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);
