binary2decimal: Binary encoding of decimal numbers and viceversa.

In GA: Genetic Algorithms

Description

Functions for computing binary to decimal conversion of numbers and viceversa.

Usage

decimal2binary(x, length)
binary2decimal(x)

Arguments

x	input value.
length	an optional value giving the length of binary string to return.

Details

decimal2binary converts a numerical value (which is forced to be an integer) to a binary representation, i.e. a vector of 0s and 1s. For real numerical values see the example below.

binary2binary converts a binary value, i.e. a vector of 0s and 1s, to a decimal representation.

Examples

# for integer values
dval <- 12
(bval <- decimal2binary(dval))
binary2decimal(bval)

# for real values
dval <- 12.456
# use
(bval <- decimal2binary(dval*1000))
binary2decimal(bval)/1000
