PGAGetRealFromBinary(1)
NAME
PGAGetRealFromBinary - Interpets 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 PGAGetRealFromBinary(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 = PGAGetRealFromBinary(ctx, p, PGA_NEWPOP, 10, 29, -10.0, 20.0);
