float array to int, is it possible?

Question

Java

There is an array of float type, I need to get its value in int multiplied by 100
That is, if the float array has a value of 0.4, then in the int array it should be 40
How can I do this? Couldn't figure out anything understandable.

Answer 1

float []arrFloat = {2.0, 0.1, 0.02};
int []arrInt = new int[3];
for(int i = 0; i < 3; i++){
    arrInt[i] = (int)(Math.round(arrFloat[i]*100))
}

That being said, when using just (int)(arrFloat[i]*100) you will get the problem of rounding negative numbers.

Answer 2

Math.round(0.4 * 100)
