can’t convert complex to float
When you try to convert a complex number to a float, you will get a TypeError because a complex number cannot be represented as a float.
A complex number consists of a real and an imaginary part, and cannot be represented by a single float value. Instead, you can convert the real or imaginary part of a complex number to a float by using the real
or imag
attribute, respectively. For example:
phpz = 3 + 4j print(float(z.real)) # Output: 3.0 print(float(z.imag)) # Output: 4.0
Alternatively, you can convert the complex number to a string using the str()
function or the format()
method, which will display the real and imaginary parts separated by a ‘+’ or ‘-‘. For example:
pythonz = 3 + 4j print(str(z)) # Output: (3+4j) print('{0.real}+{0.imag}j'.format(z)) # Output: 3.0+4.0j

Can t convert complex to float
It is not possible to convert a complex number to a float number in general, as a complex number has both a real and imaginary part, whereas a float number only has a single real part.
However, you can convert the real part of a complex number to a float using the float()
function. For example:
python>>> c = 3 + 4j >>> float(c.real) 3.0
Note that this only returns the real part of the complex number as a float, discarding the imaginary part. If you want to convert the entire complex number to a string representation, you can use the str()
function. For example:
python>>> c = 3 + 4j >>> str(c) '(3+4j)'
Convert complex to float Python
To convert a complex number to a float in Python, you can use the real
attribute of the complex number object. The real
attribute returns the real part of the complex number as a float.
Here’s an example:
pythonz = 3 + 4j z_float = z.real print(z_float) # Output: 3.0
In this example, z
is a complex number with a real part of 3 and an imaginary part of 4. We then use the real
attribute of z
to extract the real part of the complex number and store it in the variable z_float
. The print
statement then outputs the value of z_float
, which is 3.0 as a float.
