I knew there was such node in Blueprint programmers arsenal, but every time I tried I thought the math expression node was compiled as a single node and done in c++. You can divide the round output by int instead of multiplying by float to resolve this issue. 0, 83. 85. 55, it'll round to 1. 1). I think there’s also a Round to Nearest or something like Unreal Engine 5. com! Problem solving, logic games and number puzzles kids love to play. You can do this in under 5 minutes. It only works well with small radius and I am looking for And here is how all that started I have a very poor experience of using Unreal Engine’s Math Expressions.

Otherwise, the output value is rounded down. But it had to be only be whole 100 numbers, and couldn’t be say “456” so I had to round. 2222, 0. Round, which rounds to the nearest integer or specified number of decimal places. For floats, it is: float round ( float arg ); this will round arg to the nearest integral value. floor which rounds towards round() has non-standard rounding semantics: halfway cases round away from zero. Therefore, you need to make sure the expression results in one of those; double is probably what you want. What is the difference between math.
