I m looking for ways of converting an array of byte values in DWord using Ruby.
For example: [255,1,255,2] -> 11111111 00000001 11111111 000000010
因此,我需要一种办法,与DWord的任何Bete(或Word)合作,并从事比照作业。
是否有任何人建议采用一种方法,将4个沥青阵列转换为DWord,然后使用Bytes,从而产生DWord?

你可以总结一下你在课堂上的逻辑。 这里是一个脱节的例子(需要加上边界和错误检查)。
class Byte
attr_accessor :value
def initialize(integer)
@value = integer
end
def to_s
value.to_s(2).rjust(8,"0")
end
end
class DWord
attr_accessor :bytes
def initialize(*byte_list)
@bytes = []
byte_list.each do |b|
@bytes << Byte.new(b)
end
end
def to_s
@bytes.map(&:to_s).join( )
end
end
你可以做与Word、QWord等类似的事情。 以上将允许你这样做:
dword = DWord.new(255,1,255,2)
puts dword
# 11111111 00000001 11111111 00000010
dword.bytes.each do |b|
puts "#{b.value} = #{b}"
end
# 255 = 11111111
# 1 = 00000001
# 255 = 11111111
# 2 = 00000010

"101".to_i(2) => 5
以及
5.to_s(2) => "101"
很容易转化成其他基地(其基础是论点)。

并检查Ruby BilwiseOperationtors。
首先,将阵列转化为你能够做到的ice:
puts [255,1,255,2].map{|val| val.to_s(2).rjust(8, 0 )}.join( )
对双轨业务来说,这很简单。 它使用C类经营者:
OR => 1 | 2 = 3
AND => 1 & 2 = 0
XOR => 1 ^ 3 = 2
