导包import numpy as np

ceil floor rint abs nevigate square sqrt modf isnan

ceil向上取整,floor向下取整,rint四舍五入,abs取绝对值,nevigate消极的,square平方,sqrt平方根,modf将小数部分和整数部分分开,isnan 查询是否为空

arr1=np.random.uniform(-5,10,(3,4))
print(arr1)
print('ceil')
print(np.ceil(arr1))
print('floor')
print(np.floor(arr1))
print('rint')
print(np.rint(arr1))
print('abs')
print(np.abs(arr1))
print('negative')
print(np.negative(arr1))
print('square')
print(np.square(arr1))
print('sqrt')
print(np.sqrt(np.abs(arr1)))
print('modf')
print(np.modf(arr1))
print(np.modf(arr1)[0])
print(np.modf(arr1)[1])
print('isnan')
print(np.isnan(arr1))
