Did you try NumberFormat? It will round the number as needed.

when i'm using numberformat it will not help me
ex i use lbl_Result.Text = NumberFormat(CosD(lbl_Result.Text),0,1)

cos(60) = 0.5 its fine
cos(30) = 0.9 this is the problem

how i could make cos(60) = 0.5 cos(30) = 0.866025 at the same
thanks

Have you tried this ?

B4X:

Log(NumberFormat(SinD(30),1,6))

Best regards.
