binaryLogic (version 0.3.9)

binary: Binary digit.

Description

Create objects of type binary.

Usage

binary(n, signed=FALSE, littleEndian=FALSE)

Arguments

n

length of vector. Number of bits

signed

TRUE or FALSE. Unsigned by default. (two's complement)

littleEndian

if TRUE. Big Endian if FALSE.

Value

a vector of class binary of length n. By default filled with zeros(0).

Details

The binary number is represented by a logical vector. The bit order usually follows the same endianess as the byte order. How to read:

• Little Endian (LSB) ---> (MSB)

• Big Endian (MSB) <--- (LSB)

The Big Endian endianess stores its MSB at the lowest adress. The Little Endian endianess stores its MSB at the highest adress.

e.g. b <-binary(8).

• "Little Endian" : MSB at b[1] and LSB at b[8].

• "Big Endian" : LSB at b[1] and MSB at b[8].

No floating-point support.

Examples

# NOT RUN {
b <- binary(8)
summary(b)
b <- binary(16, signed=TRUE)
summary(b)
b <- binary(32, littleEndian=TRUE)
summary(b)
# }
