if ( sin ( $F ) < 0 , 0 , sin ( $F )) ?
or if you regret double sin() evaluation
{
float s = sin ( $FF );
if ( s < 0 )
return 0 ;
return s ;
}
although I don't believe it's a big issue here
…or clamp as mentioned bellow

Hello. Your question is being a bit complex for doing that by expression. I create simple HIP file so that you can control attributes of wave via green node. hope it helps.
