Convert a float value to a 2 byte int?

Projects Programming

So i v casted a float value by saying

float val;
int myInt = (int)val;

however this integer still appears to be 4 bytes long and i want to transmit it as a 2 byte integer. is there a way to convert a 4 byte int to 2 bytes?

It is not. You'll have to explain why you are operating under this incorrect assumption.

Integer on the Arduino is 2 bytes.

How do you know it isn't 2?

Arduino DUE or what?

The type "int" is platform dependent.

If you want 2-byte integers, use "int16_t" in your variable declaration!

sorry about this post, i tried to delete it earlier but i couldnt. the integer is in fact 2 bytes. I was sending the integer via serial.println so extra bytes were because i was sending the integers as characters.
