我们可以通过多种方式将 Float 数组转换为 Int 数组。一种常见的方法是使用numpy库中的astype方法。以下是实现代码: defconvert_float_array_to_int(float_array):# 将浮点数数组转换为整数数组returnfloat_array.astype(int)# 调用函数进行转换int_spending=convert_
importnumpyasnpimporttime size=10**6float_array=np.random.rand(size)*100start=time.time()int_array=float_array.astype(int)end=time.time()print(f"astype:{end-start}seconds")start=time.time()int_array=np.round(float_array)end=time.time()print(f"round:{end-start}seconds")start=time.time...
将整数的字符串表示形式传递给 int将float的字符串表示形式传递给 float将整数的字符串表示形式传递给 float将一个浮球传递进去 int将整数传入 float 但是,你得到一个ValueError,如果你传递的字符串表示浮到int,或任何一个字符串表示,但一个整数(包括空字符串)。如果你确实想要将float的字符串表示传递给 int,你可以...
7 dd = int("34a") #Error,Can't Convert to int 8 print "dd = ",dd 9 ee = int("12.3") #Error,Can't Convert to int 10 print ee 11 二、float函数将整数和字符串转换成浮点数。 举例: 1 aa = float("124") #Correct 2 print "aa = ", aa #result = 124.0 3 bb = float("123....

Convert a string or number to a floating point number, if possible. 可以接收Int和String类型参数,float()函数在连接数据库操作会被经常使用。当参数为String时,只能出现数字和一个点额任意组合,若出现多个点号,则会出现异常。 In[194]:float(10)Out[194]:10.0In[195]:float('100')Out[195]:100.0In[19...
Correctly convert Python float to float64 when passing argument as Tensor (#136413) I can't actually test the Dynamo codegen fix as it is impossible to directly use the Tensor at the moment. Signed-off-by: Edward Z. Yang <ezyang@meta.com> Pull Requestresolved:#136413Approved by:https:/...
