@ustk yeah it has to resolve two things (the object t and the function getIntValue) vs. one (only the object, the math function is resolved at compile time.
But this performance difference is neglible - in UI contexts there are much slower things and if you are using anything string related in an audio processing context you have to sit back and evaluate life decisions that lead you into this situation of misery anyway.
Also Math.round still returns a float number IIRC while getIntValue makes sure that the var instance uses the integer data slot internally.
