Floating Point Numbers
In Python, floating point numbers (decimals) are used to represent numbers instead of integers.
Some examples of numbers are represented as 0.5 and -7.8237591.
They can be created directly by entering numbers with a decimal point or by using operations like integer division.
Computers cannot store floating point numbers (decimals) with complete precision, just as we cannot write out the complete decimal representation of 1/3 (0.3333333333333333).
Keep this in mind, as it often leads to annoying program bugs!
Integer Division Results in Floating Point Numbers
As mentioned earlier, dividing any two integers will produce a floating point number.
Performing operations on two floating point numbers, or on a floating point number and an integer, will yield a floating point number.
>>> 8/24.0
>>> 6*7.042.0
>>> 4+1.655.65Python silently converts integers to floating point numbers.
0 Cannot Be a Divisor
Dividing any number by 0 in Python will result in an error.
>>> 11/0
ZeroDivisionError: division by zeroIn Python, the last line of the error message indicates the type of error. Read the error message carefully, as it often tells you how to fix the program!
