question about multiplication Ok, I think I get it. This mean that the function for multiplying two 16-bit value will return the result like 16-bit integer, and when emphasize (int32_t) before 16-bit values,...

readout PC3 set PD0 try this
if(PINC&(1<<PINC3))
PORTD |=(1<<PD0)
else
PORTD &= ~(1<<PD0)

question about multiplication Hi, I need 32-bit data from multiplying two 16-bit data, because a and b have value around (+-)10 000, that is why I use int32_t c, but my question is why, if I have the variable...

Problem with fixed point math Jim, the problem is with numbers between -0.9999 and -0.0001.
In the macro he test is A0 (A is whole part of number) and then determine sign (A can be -1, 0 or 1), but what if the...

Problem with fixed point math @ cmhicks
yes, I know that I need to get that, but the problem is with macro, I think I found solution to use only numbers from 0 to 1.9999....

Ok, you are right, I was a little confused with statement step = -1 or step *= -1, since it was defined as unsigned, but now I get it, thanks.
