Java rounding up to an int using Math.ceil

Question

int total = (int) Math.ceil(157/32);

Why does it still return 4? 157/32 = 4.90625, I need to round up, I\'ve looked around and this se

Answer 1

I know this is an old question but in my opinion, we have a better approach which is using BigDecimal to avoid precision loss. By the way, using this solution we have the possibility to use several rounding and scale strategies.

final var dividend = BigDecimal.valueOf(157);
final var divisor = BigDecimal.valueOf(32);
final var result = dividend.divide(divisor, RoundingMode.CEILING).intValue();
