java - Is performance of "Math.abs()" better than expression with "if"? -

i have expression:

double getabs(double value){ return value> 0 ? value: value== 0 ? null : -value; }

or better:

 double getabs(double value){ return math.abs(value); }

i understand there differences nan. method math.abs(double) - have unboxing. in case performance better?

the "performance" in code jvm need unbox double double.

math.abs(double) uses ternary if statement follows:

public static double abs(double a) {     return (a <= 0.0d) ? 0.0d - : a; }

so, if statement no performance worry @ all.
