ST0.d!=0.0 can we judge double value != 0.0 through this?

hi, thanks for your great work. just some question. void arm_fscale(x64emu_t* emu) { if(ST0.d!=0.0) // can we judge double value != 0.0 through this? ST0.d *= exp2(trunc(ST1.d)); }

That should be correct yes, why, you have some issue with this?

thanks for reply. not still have issue with this, just learned fron classs ,say that ‘if( abs(f) <= 1e-15 )，then f=0’’,i will test it later.. i got there because i am going through all the helper function, and check is there more Optimization could be done.
