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

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);
