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...
Here we are going to convert the float type column in DataFrame to integer type usingastype()method. we just need to passintkeyword inside this method. Syntax: dataframe['column'].astype(int) where, dataframe is the input dataframe column is the float type column to be converted to integer...

In SQL, it is common to store data in different formats like VARCHAR, INT, FLOAT, etc. based on the needs of the application. However, sometimes we may need to convert a VARCHAR column to an INT for performing arithmetic operations, comparisons or other logical queries that require integer ...
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
