- Converting real numbers to complex number An complex number is represented by “ x + yi “.
Python converts the real numbers x and y into complex using the function complex(x,y).
The real part can be accessed using the function real() and imaginary part can be represented by imag(). - Python lets you use complex numbers in arithmetic expressions and call functions on them just like you would with other numbers in Python.
It leads to elegant syntax that reads almost like a math textbook. - Python Programming offers a built-in round() function which rounds off a number to the given number of digits and makes rounding of numbers easier.
The function round() accepts two numeric arguments, n and n digits then returns the number n after rounding it to digits. - Python's Built-in round() Function
Python has a built-in round() function that takes two numeric arguments, n and ndigits , and returns the number n rounded to ndigits . - The Python round() function follows the half to even rounding strategy.
In this strategy, the number is rounded to its nearest even integer.
For example, if we need to round off 7.5, it will be rounded off to its nearest even integer, 8.
But if we need to round off 6.5, it will be rounded off to 6 as it is closer to 6.
