parameter convert_float will convert "integral floats to int (i.e., 1.0 –> 1)", but take care with corner cases like NaN's. This parameter is only available in read_excel To make the conversion in an existing dataframe several alternatives have been given in other comments, but since v...
Note:When we convert float to int Python,the int() functiontruncates the decimal part of the number rather than rounding it to the nearest whole number. If we need rounding, we should usethe round() functionbefore converting to an integer. How to convert negative float value to int in Py...
需要注意的是,如果直接将float数转换为字符串,可能会失去一些精度信息。因此,在实际应用中,我们通常会先将float数转换为整数或分数形式,然后再将其转换为字符串。例如: float_num=3.14159265int_num=int(float_num)fraction_num=float_num-int_num str_num=str(fraction_num)print(str_num)# 输出 "0.14159265" ...
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 ...
# 将字符串转成int或float时报错的情况 print(int('18a')) # ValueError: invalid literal for int() with base 10: '18a' print(int('3.14')) # ValueError: invalid literal for int() with base 10: '3.14' print(float('45a.987')) # ValueError: could not convert string to float: '45a.98...
int_num=10float_num=10.0 In the above example,int_numis an integer, whilefloat_numis a float. Why Convert Float to Int? You might be wondering, why would we need to convert a float to an integer? The answer lies in the specific requirements of your program. Sometimes, a decimal value...
