print(1+2.0)# prints 3.0 Run Code Here, we can see above that1(integer) is converted into1.0(float) for addition and the result is also a floating point number. Explicit Type Conversion We can also use built-in functions likeint(),float()andcomplex()to convert between types explicitly....
tracking of significant decimal places, or applications where the user expects the results to match calculations done by hand.For example, calculating a 5% tax on a 70 cent phone charge gives different results in decimal floating point and binary floating point. The difference becomes significant ...
