Question

How to convert a double value to int doing the following:

Double If x = 4.97542. Convert to int x = 4.

Double If x = 4.23544. Convert to int x = 4.

That is, the answer is always rounding down.

Answer 1

If you explicitly cast double to int, the decimal part will be truncated. For example:

int x = (int) 4.97542;   //gives 4 only
int x = (int) 4.23544;   //gives 4 only

Moreover, you may also use Math.floor() method to round values in case you want double value in return.
