Can we convert float to int in python?
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). Converting an int value like 2 to floating-point will result in 2.0, such types of
conversion are safe as there would be no loss of data, but converting 3.4 to an int value will result in 3 leading to a lossy conversion. Show Input: 3.3 Output: 3 Input: 5.99 Output: 5 Method 1: Conversion using int(): To convert a float value to int we make use of the built-in int() function, this function trims the values after the decimal point and returns only the integer/whole number part.
Example 1: Number of type float is converted to a result of type int. Python3
Output type: float converted value: 9 , type: int Example 2: In most cases the int() function rounds off the result to an integer lesser than or equal to the input, but the behavior is neither definite nor predictable. One such example is shown below. Python3
Method 2: Conversion using math.floor() and math.ceil(). A float value can be converted to an int value no larger than the input by using the math.floor() function, whereas it can also be converted to an int value which is the smallest integer greater than the input using math.ceil() function. The math module is to be imported in order to use these methods.
Example : In the below example conversion from float to int has been achieved using the floor() and ceil() methods, the former returns an int no larger than the input and the latter returns the smallest integer larger than the input. Python3
Output the result using floor() : 5 , type : int the result using ceil() : 6 , type: int Method#3: Conversion using round( ). A float value can be converted to an int value which is closet integer value if does not pass second parameter. In case of equal difference it goes toward larger integer.
Example : In the below example conversion from float to int has been achieved using the round() methods, the former returns an int number which is closest to number. Python3
Output Type : float Original number is : 5.6 Type : int the result using round : 6 Method#4: Conversion using math.trunc( ). A float value can be converted to an int value. In case of negative number it behaves like ceiling function of math library and in case of positive number it behaves like floor function..
Example : In the below example conversion from float to int has been achieved using the math.trunc() methods, the former returns an larger int number which in case of negative number, else in case of positive number return smaller integer number. Python3
Output Type of value : int the result using round : -2 Type of data: int the result using round : 5 Can float convert to int?A float value can be converted to an int value no larger than the input by using the math. floor() function, whereas it can also be converted to an int value which is the smallest integer greater than the input using math. ceil() function.
What happens when you convert a float to an int Python?Convert a float to an int always results in a data loss. The trunc() function returns the integer part of a number. The floor() function returns the largest integer less than or equal to a number.
How do I change Dtype from float to int?The df. astype(int) converts Pandas float to int by negelecting all the floating point digits. df. round(0).
Does Python automatically convert int to float?Integers and floating-point numbers can be mixed in arithmetic. Python 3 automatically converts integers to floats as needed.
