如何将x.0更改为x？

Question

in 120/10 result is 12.0 I want res to be 12 in float mode can I change 12.0 to 12?

Float x =120f;
Float y =10f;
res.setText(x/y);

finally res> 12.0

Answer 1

将它转换为int。

res.setText((int)(x/y));

Answer 2

Use String.format()

String.format("%.1f", 12.0f); //returns "12,0"
String.format("%.0f", 12.0f); //returns "12"
String.format("%.1f", 120f / 10f); //returns "12,0"
String.format("%.0f", 120f / 10f); //returns "12"

Answer 3

Similar to @ronmrdechai's answer, only if you want to round the result, which will be something like

int result = (int)(x/y + 0.5f);
res.setText(Integer.toString(result));

Answer 4

Float x =120f;
Float y =10f;
res.setText((int)(x/y));

You have to cast it to an int . That, or make their types ints / Integers originally.
