how to implement the power of 2 of a floating number?

[milan.km]

Hi,
I would really apreciate if sb help me to calculate the power of two of a floating point number with FPGA?

 

[ads-ee]

floating point? Are you sure you want floating point?

By power of two do you mean this?

2**(some floating point number), e.g. 2**1.23456e-15

two raised to a floating point value...

Look at the following algorithm descriptions.

Both describe algorithms for non-integer exponentiation.
