- What does this little program do? You will want to bring up the Serial Monitor to find out.
void
setup()
{
Serial.begin( 115200 );
Serial.print( 4 * atan(1), 7 );
}
void
loop()
{
}
- How about this little program?
void
setup()
{
Serial.begin( 115200 );
Serial.println( 3., 7 );
Serial.println( 3. + 4./(2*3*4), 7 );
Serial.println( 3. + 4./(2*3*4) - 4./(4*5*6), 7 );
Serial.println( 3. + 4./(2*3*4) - 4./(4*5*6) + 4./(6*7*8), 7 );
Serial.println( 3. + 4./(2*3*4) - 4./(4*5*6) + 4./(6*7*8) - 4./(8*9*10), 7 );
Serial.println( 3. + 4./(2*3*4) - 4./(4*5*6) + 4./(6*7*8) - 4./(8*9*10) + 4./(10*11*12), 7 );
}
void
loop()
{
}
- Or this one?
long double magic = 3.;
bool add = true;
void
setup()
{
Serial.begin( 115200 );
for( long int x = 2; x <= 200; x += 2 )
{
long double denom = x * (x+1) * (x+2);
if( add )
magic += 4. / denom;
else
magic -= 4. / denom;
add = ! add;
Serial.println( (double) magic, 7 );
}
}
void
loop()
{
}
