Python - Numeric Mixed types
Introduction
You can mix numeric types. For instance, you can add an integer to a floating-point number:
40 + 3.14
In mixed-type numeric expressions, Python converts operands up to the type of the most complicated operand, and then performs the math on same-type operands.
Python ranks the complexity of numeric types like so:
- integers are simpler than floating-point numbers, which are simpler than complex numbers.
So, when an integer is mixed with a floating point, the integer is converted up to a floating-point value first, and floating-point math yields the floating-point result:
Demo
print( 40 + 3.14 ) # Integer to float, float math/result
Result
You can force the issue by calling built-in functions to convert types manually:
Demo
print( int(3.1415) ) # Truncates float to integer print( float(3) ) # Converts integer to float
Result
