How to find One's complement of floating point variable ?

4 views (last 30 days)
Hi,
I used Simulink Bitwise Not operator to find the one's complement of uint8 type variable.
Now I want to find one's complement of float variable (double) using simulink.
Can you please help me on how to perform the task.
Thank you

What does a 1's complement of a floating point bit pattern even mean to you? How do you intend to use this result?

I need to convert float variable to binary number and then find one's complement of that, covert it into float variable again.
I am using it for redundancy validation.

typecast to uint64, take the one's complement, typecast back.
Caution: 1's complement of 0.0 is NaN.

yes, I want decimal representation of the one's complement.
The function which Walter recommened worked.

@Paul note in particular they wanted the one's complement of the binary representation of double precision numbers, not of an integer data type.
