Float() is a built-in Python function that converts a number or a string to a float value and returns the result. If it fails for any invalid input, then an appropriate exception occurs.

Celsius vs. Fahrenheit

Celsius and Fahrenheit are the same at – 40 degrees since the scales converge. Celsius and Kelvins become equal at high temperatures as the difference of 273.15 between them gets lost in the noise. 0 degrees Celsius is equal to 32 degrees Fahrenheit.

We can convert a string to float in Python using float() function. It’s a built-in function to convert an object to floating point number.

Integers and floats are data types that deal with numbers. To convert the integer to float, use the float() function in Python. Similarly, if you want to convert a float to an integer, you can use the int() function.

Number Type Conversion

1. Type int(x) to convert x to a plain integer.
2. Type long(x) to convert x to a long integer.
3. Type float(x) to convert x to a floating-point number.
4. Type complex(x) to convert x to a complex number with real part x and imaginary part zero.

Python allows you to assign a single value to several variables simultaneously. Here, two integer objects with values 1 and 2 are assigned to the variables a and b respectively, and one string object with the value “john” is assigned to the variable c.

Import numpy module using the import numpy as np statement. Pass float numbers to its start, stop, and step argument. For example, np. arange(0.5, 6.5, 1.5) will return the sequence of floating-point numbers starting from 0.5 up to 6.5.

Because floating-point numbers represent real numbers, it is often mistakenly assumed that they can represent any simple fraction exactly. Different implementations have different precision limitations, and to keep code portable, floating-point variables must not be used as the loop induction variable.
