Detailed Description

Function Documentation

ITPP_EXPORT bvec itpp::oct2bin	(	const ivec &	octalindex,
		short	keepzeros = 0
	)

Convert ivec of octal form to bvec.

Converts from ivec containing {0,1,2,...,7} to bvec containing {0,1}. Removes zeros to the left if keepzeros = 0 (default). Example: oct2bin("3 5 5 1") returns {1 1 1 0 1 1 0 1 0 0 1}.

ITPP_EXPORT ivec itpp::bin2oct

(

const bvec &

inbits

)

Convert bvec to octal ivec.

Converts from bvec containing {0,1} to ivec containing {0,1,2,...,7}. Adds zeros to the left if inbits.length() is not a factor of 3. Example: bin2oct("1 1 1 0 1 1 0 1 0 0 1") returns {3 5 5 1}.
