# float to int python

The int() function works similarly to the float() function: you can add a floating-point number inside of the parentheses to convert it to an integer:. Integers and floating points are separated by the presence or absence of a decimal point. We looked at int, float, and complex numbers. Python has built-in methods to allow you to easily convert integers to floats and floats to integers. The above example contains 10 as the float value before the decimal point. Then we looked at how to convert one numeric type into another in Python. Returns: Smallest integer not less than x. Call it with a string containing a number as the argument, and it returns the number converted to an integer: You have to use the int() function of Python. Here we have used NumPy Library. That's not the case in a quick test I just did with numbers like 1.5, 2.5, 3.5 and so on and 1.05, 1.15, 1.25, 1.35 rounding to one decimal place. To print the resulted integer value after conversion, you have to use the Python print() function. print(type(string_to_number("12.4"))) string that is a string. Examples: 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.
