Arithmetic Operations ABS r3 = abs r1 ; a1 = abs a1, a0=abs a0 ; Add/Subtract r5 = r2 + r1(s) ; r0.l = r2.h + r4.l(ns) ; r1.l = r6-r7(rnd20) ; r1.l = r6-r7(rnd12) ; r0 += 40 ; MAX /MIN r5 = max (r2, r3) ; r5 = min (r2, r3) (v); Multiply r3.h=r6.h*r4.l (fu) ; r3 *= r0 ; a1+=r6.h*r4.l (fu) ; r3.h=(a1+=r6.h*r4.l) (fu) ; r3=(a1+=r6.h*r4.l) (fu) ; Negate a1 =-a1, a0=-a0 ; SIGNBITS r0.l = signbits r4.h ; r6.l = signbits a0 ;
