[avr-gcc-list] computing sine & cosine

[nurdin]

    im beginner on avr,my project needs the avr ability using trigonometrical 
funtion such as sine, cosine, etc.
    i've read that to use trigonometrical function we should use float 
number,question:
    1.how's the digital representation of float number in avr?
    2.how's to check avr's ability in using trigonometrical functions 
(sine,cosine,etc) ?

    thanx before
    best regards,
