Hey guys

In my adventures with programming I've come across a weird little thing when testing values from the cos() in math.h on ubuntu!

heres my output from a for loop that does this:

for(int i = 0; i<=360; i++ ) {

cout << "angle = " << i << " Radians = " << cos(i*M_PI/180) << "\n";

}

OUTPUTS:

all seems fine untile i get to 90 degrees then its seems to go nuts!

anyone else get this?

In my adventures with programming I've come across a weird little thing when testing values from the cos() in math.h on ubuntu!

heres my output from a for loop that does this:

for(int i = 0; i<=360; i++ ) {
