Say i have
Log.e("deg: "+dd, "X:"+ Math.sin( Math.toRadians(dd) ) +"| Y:"+Math.cos( Math.toRadians(dd) ) );
if dd = 180, then sin should be 0 and cos -1 , right? but it outpusts
deg: 180 X:1.2246467991473532E-16| Y:-1.0
any ideas? Thanks!
The value
1.2246467991473532E-16is effectively zero, to 16 decimal places; it’s0.00000000000000012246.You just need to format the number for display, if that’s the problem.
