Float value into bytes

Posted: Tue Apr 09, 2013 4:25 am

Hello everybody!
I try to divide a float value like this

Code:

float temperature;
temperature = 23.5;
dec = int(temperature / 10);// must be 2

I want to have int "2" in dec variable.
When i compile, i get an error

Quote:

A numeric expression must appear here

How can i split float value into separate bytes?

Your syntax is wrong. Missing brackets:

Code:

float temperature;
temperature = 23.5;
dec = (int)(temperature / 10);// must be 2

You are telling it to call a function called 'int', not convert the result to an int....

Best Wishes

Thank you very much.
I have one more question.
I need convert to string, ASCII string

Code:

dec = (int)(temperature / 10);

P.S. I found answer, thanks to all
