### 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:

php`z = 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:

python`z = 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:

python`z = 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.
