The followi ng Sial operators were added in August 2014 to allow native code com-
pilation of the floating point features.
float a := FLOAT a; b := ?
fix a := FIX a; b := ?
fabs a := #ABS a; b := ?
fneg a := #- a; b := ?
fmul a := b #* a; b := ?
fdiv a := b #/ a; b := ?
fadd a := b #+ a; b := ?
fsub a := b #- a; b := ?
feq a := b #= a; b := ?
fne a := b #~= a; b := ?
fls a := b #< a; b := ?
fgr a := b #> a; b := ?
fle a := b #<= a; b := ?
fge a := b #>= a; b := ?
feq0 a := a #= 0; b := ?
fne0 a := a #~= 0; b := ?
fls0 a := a #< 0; b := ?
fgr0 a := a #> 0; b := ?
fle0 a := a #<= 0; b := ?
fge0 a := a #>= 0; b := ?
The floating point conditional jump instructions are as fol l ows.
