PGAGetRealFromBinary1

Interpets a binary string as encoding a real value and returns the real value it represents.

Usage

PGAContext *ctx

int p

int pop

int start

int end

double lower

double upper

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

Location

Examples

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);
