Print(abs(3+4j))

Question

What does it mean?
And how it gives as output 5.0

Answer 1

3+4j is a complex number:
real part = 3
imaginary part = 4

absolute value of complex number (modulus) = sqrt(Re**2 + Im **2):
sqrt(3**2 + 4**2) = sqrt(25) = 5

Answer 2

You can use the Pythagoras theorem to determine the modulus/size/absolute value of a complex number.

Answer 3

it depends on argument:
for int argument abs() returns int
for float and complex argument it returns float

Answer 4

It's a modulus of complex number.

Answer 5

Then, what's the function of abs

Answer 6

Does abs function return float value
