BitArrays

This module implements a few functions for constructing Base.BitArray objects.

bitarray!(vector::AbstractVector{<:Unsigned}, [dims]) where {T}

Return a BitArray with dimensions dims using vector as chunks.

If vector is not a Vector, it will be copied. If vector is a Vector{T} then it will be reinterpreted to T == UInt64 after possible padding.

Examples

julia> (bitarray!([UInt8(1), UInt8(2)]),)
(Bool[1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0],)

bitarray(x::Union{Integer, Base.IEEEFloat}, [dims])

Return a BitArray from the bits in x.

Examples

julia> (bitarray(typemax(UInt16)),)
(Bool[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1],)

julia> bitarray(typemax(UInt16), (2, 8))
2×8 BitMatrix:
 1  1  1  1  1  1  1  1
 1  1  1  1  1  1  1  1

bitvector(x::Union{Integer, Base.IEEEFloat})

Return a BitVector with the bits in x.

Examples

julia> (bitvector(UInt8(11)), )
(Bool[1, 1, 0, 1, 0, 0, 0, 0],)

julia> bstring(bitvector(UInt64(1<<32 -1)))
"1111111111111111111111111111111100000000000000000000000000000000"

julia> typeof(bitvector(UInt64(1<<32 -1)))
BitVector (alias for BitArray{1})
