Python program to round when converting float to integer# Importing pandas package import pandas as pd # Importing numpy package import numpy as np # Creating a dictionary d = {'a':[4.5,6.7,6.4,2.4,7.5]} # Creating a DataFrame df = pd.DataFrame(d) # Display Original df print("Original...
Converting float to integer may impact performance, especially with large datasets, due to the change in memory usage. NaN values in float columns must be handled before conversion, as integers do not support NaN. Quick Examples of Pandas Convert Float to Integer ...
有时会遇到类似于ValueError: cannot convert float NaN to integer的错误。
df.round(0).astype(int)rounds the Pandasfloatnumber closer to zero. This method provides functionality to safely convert non-numeric types (e.g. strings) to a suitable numeric type. s=pd.Series(["1.0","2",-3])print(pd.to_numeric(s,downcast="integer")) ...

It is also possible to transform multiple variables to a different data type. In Example 2, I’ll show how to change the data class of two variables from integer to float. Once again, we can use the astype function for this: data_new2=data.copy()# Create copy of DataFramedata_new2=...
