NumPy - 右移

• 

  简述

  numpy.right_shift()函数将数组元素的二进制表示中的位向右移动指定位置，并从左侧附加相同数量的 0。

  
  import numpy as np 
  print 'Right shift 40 by two positions:' 
  print np.right_shift(40,2) 
  print '\n'  
  print 'Binary representation of 40:' 
  print np.binary_repr(40, width = 8) 
  print '\n'  
  print 'Binary representation of 10' 
  print np.binary_repr(10, width = 8)  
  # Two bits in '00001010' are shifted to right and two 0s appended from left.

  它的输出如下 -

  
  Right shift 40 by two positions:
  10
  Binary representation of 40:
  00101000
  Binary representation of 10
  00001010
