Find the Largest of 3 Values

I trying to figure out how to find the largest of 3 values. I got fairly close using if/else statements but it always breaks somewhere. Ideally I would like to get the 3 values as small, med and large. Thanks.

Here's where I left off:

if (a > b) {
if (a > c){
v = a
}
else {
if (b > c){
if (b > a)
v = b
}
else {
if (c > a)
v = c
}
}
}
else {
v = c
}

i think you could do it with this:

Math.max(Math.max(a,b),c);

if you needed more values, you'd need to embed them in more Math.max() functions, ex:

Math.max(Math.max(Math.max(a,b),c),d);

you know, i've always thought it should work that way, but never tried it -- though i've rarely needed it...

thanks.

Yeah, it looks like it didn't get fixed until CS6. Safer to do it your way.

i think this would work...

vals = [a,b,c];
max = Math.max(Math.max(a,b),c);
min = Math.min(Math.min(a,b),c);
for (i = 0; i < vals.length; i++){
if (vals[i] > min && vals[i] < max) mid = vals[i];
}
mid

Try this:

max = Math.max(Math.max(a,b),c);
min = Math.min(Math.min(a,b),c);
if (a < max){
if (a > min) mid=a else mid=Math.min(b,c);
}
else {mid = Math.max(b,c)};
mid

It will hardly generalize to higher number of parameters but for just 3 it is ok.

Here's an alternate approach, using arrays and the sort() method. First, stuff each of the values into an unsorted array. Next, sort the array. Finally, return the value of the last item in the array, which will be the highest value because we just sorted it.

unsortedArray = [a,b,c];
sortedArray = unsortedArray.sort();
sortedArray[sortedArray.length-1];

To get the middle value, replace the final line with:sortedArray[Math.round(sortedArray.length/2)-1];

To get the lowest value, replace the final line with:sortedArray[0];


You can shorten it, too, removing the assignment:
myArray = [a,b,c];
myArray.sort()[sortedArray.length-1];
