Code:

math.sqrt( math.pow( xa - xb, 2 ) + math.pow( ya - yb, 2 ) + math.pow( za - zb, 2 ))

thank you ~!

Code:

fld qword [xa] //st0=xa
fsub qword [xb] //st0=xa-xb
fmul st(0) //st0=(xa-xb)^2

fld qword [ya] //st0=ya , st1=(xa-xb)^2
fsub qword [yb] //st0=ya-yb
fmul st(0) //st0=(ya-yb)^2

fld qword [za] //st0=za , st1=(ya-yb)^2 , st2=(xa-xb)^2
fsub qword [zb] //st0=za-zb
fmul st(0) //st0=(za-zb)^2

faddp st(2),st(0)//st0=(ya-yb)^2 , st1=(xa-xb)^2+(za-zb)^2
faddp st(1),st(0)//st0=(xa-xb)^2+(za-zb)^2+(ya-yb)^2
fsqrt //st0=sqrt( (xa-xb)^2 + (za-zb)^2 + (ya-yb)^2 )
fstp qword [result] //store the resut

Replace qword by dword if you're using floats instead of doubles.
