The round functions in the np, ceil function and floor function

np.round()

import numpy as np

x = [10.7, 10.5, 10.3, 11.7, 11.5, 11.3, 0.7, 0.5, 0.3]
y = np.round(x)
print(y)

• np.round()The meaning of function is round.In the theory of error,Even when the integer part of,小数部分是0.5时,向下取整;When the integer part is odd,小数部分是0.5时,则向上取整.也就是说,When the decimal part is0.5的时候,“Go odd save even”,Such results are statistically more accurate.numpy的roundFunction using that method was.
  

np.ceil()*

import numpy as np

x = [10.7, 10.5, 10.3, 11.7, 11.5, 11.3, 0.7, 0.5, 0.3]
y = np.ceil(x)
print(y)

• 向上取整
  

np.floor()

import numpy as np

x = [10.7, 10.5, 10.3, 11.7, 11.5, 11.3, 0.7, 0.5, 0.3]
y = np.floor(x)
print(y)

• 向下取整
