Im reading data from serial port as int16 class but i could not convert it into float using any of the functions float,cast,typecast. They say that int to float is not supported. somebody plz tell me how can i do typecasting from int16/uint16 to float/double???

Thnx

Do you know that "float" is called "single" in Matlab?
This should solve the problems.

If you need to typecast to float or double and you do not need to
rearrange the bytes, then read the port as float or double. If you _do_
need to rearrange the bytes, then chances are good that you have to swap
the upper and lower byte within the 16 bits, so you should read as uint8
and rearrange the bytes and typecast that.
