dear friends
I receive data from a power meter and it is a 4 bytes IEEE 754 floating point number. but I need to convert those bytes to my C compilers float type .

thanks for fast reply. as you said I try to write them in a 32 bit memory word.

Are you saying Peter's answer did not work?
The only other twist I can think of is if your power meter is big-endian and your computer is little-endian; or vice versa. See
http://en.wikipedia.org/wiki/Endianness
If that is the case, then instead of copying the four bytes from memory in order, you should reverse the byte order. e.g.
source+0 -> dest+3
source+1 -> dest+2
source+2 -> dest+1
source+3 ->dest+0
in order for the destination computer to properly interpret the IEEE 754 format.
