Float to byte conversion

[tahiticecil]

Hello everyone !

I would like to know how to convert a float number (value is always between 0 and 255) to a byte like this :
Float value 5,023 should be converted to 5 in my byte, 127.845 => 127 etc.

Any ideas ?
Best Regards,
Clément.

You mean just keep the integer part of it?

You can do:

In the general C language lingo you want to "cast" the float to an 8 bit int. The compiler should do this automatically, but to be really sure you can do what mkuang shows.

This

my_integer = (unsigned char) my_float;

is an explicit cast, whereas simply

my_integer = my_float;

should do an automatic cast.

Hi !

I hadn't thought that a simple cast could work. I tried to work directly on each bytes of a float var to get the integer part.


Thank you for your help.
