In this tutorial, we shall learn how to convert a floating point value to an integer value. Converting a float value to an int is done by Type conversion, which is an explicit method of converting an operand to a specific type.However, it is to be noted that such type of conversion may tend to be a lossy one (loss of data). Before we get in to converting strings to numbers, and converting numbers to strings, let's first see a bit about how strings and numbers are represented in Python. The df.astype(int) converts Pandas float to int by negelecting all the floating point digits. float. to another data type is called type conversion. Example 1: Python3. 8. The str() function takes an object that can be an int, float, double etc. To take input in Python, we use input() function, it asks for an input from the user and returns a string value, no matter what value you have entered, all values will be considered as strings values. The short answer is: use Python round() to change to 2 decimal places. Float() This function is used to convert any data type to a floating-point number.
