Use pandas DataFrame.astype(int) and DataFrame.apply() methods to cast float column to integer(int/int64) type. I believe you would know float is bigger
We will demonstrate methods to convert a float to an integer in a PandasDataFrame-astype(int)andto_numeric()methods. ADVERTISEMENT First, we create a random array using theNumPylibrary and then convert it intoDataFrame. importpandasaspdimportnumpyasnp df=pd.DataFrame(np.random.rand(5,5)*5)pri...
You can useDataFrame.astype(int)orDataFrame.apply()method to convert a column to int (float/string to integer/int64/int32 dtype) data type. If you are converting float, you would know float is bigger than int type, and converting into int would lose any value after the decimal. Advertisem...

Example 1: Convert Single pandas DataFrame Column from Integer to Float This example explains how to convert one single column from the integer data type tofloat. To accomplish this task, we can apply the astype function as you can see in the following Python code: ...
Here we are going to convert the float type column in DataFrame to integer type using astype() method. we just need to pass int keyword inside this method through dictionary. Syntax: python dataframe['column'].astype({"column":int}) where, dataframe is the input dataframe column is the fl...
