JS floating-point subtraction operation

Floating-point addition operations

function Floatadd (arg1,arg2) {       var  r1,r2,m;        Try {r1=arg1.tostring (). Split (".") [1].length}catch(e) {r1=0}       try{r2=arg2.tostring (). Split (".") [1].length}catch(e) {r2=0}       M=math.pow (Math.max (R1,R2))         Return (arg1*m+arg2*m)/M   }   

Floating-point subtraction operations

function floatsub (arg1,arg2) {       var  r1,r2,m,n;        Try {r1=arg1.tostring (). Split (".") [1].length}catch(e) {r1=0}       try{r2=arg2.tostring (). Split (".") [1].length}catch(e) {r2=0}       M=math.pow (Ten, Math.max (R1,R2));        // Dynamic Control accuracy length       N= (R1>=R2)? r1:r2;        return ((arg1*m-arg2*m)/m). ToFixed (n);   }   

Floating-point multiplication operations

function Floatmul (ARG1,ARG2)   {       var m=0,s1=arg1.tostring (), s2=arg2.tostring ();        Try {M+=s1.split (".") [1].length}catch(e) {}       try{m+=s2.split (".") [1].length}catch(e) {}       return number (S1.replace (".", "")) *number (s2.replace (".","")) /math.pow (10,m)   }   

Floating-point division operations

function Floatdiv (arg1,arg2) {       var t1=0,t2=0, r1,r2;        Try {t1=arg1.tostring (). Split (".") [1].length}catch(e) {}       try{t2=arg2.tostring (). Split (".") [1].length}catch(e) {}       with(Math) {           R1=number ( Arg1.tostring (). Replace (".", ""))           R2=number (arg2.tostring (). Replace (".", ""))            return (R1/R2) *pow (10,T2-T1);       }   }
