java - Doubt about strictfp and StrictMath -

i have little technical question, same call:

   public static strictfp double mymethod(double phi){        return math.exp(phi);    } 

or:

   public static double mymethod(double phi){        return strictmath.exp(phi);    } 

or strictfp keyword applies basic arithmetic operations + - * / used inside method?

if floating point expression within strictfp "scope", results predictable described in ieee 754 ...
