This is the command PGAGetRealFromGrayCode that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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);
