Like Math.Max but takes 3 or params of int?
thanks
This question is related to
c#
As generic
public static T Min<T>(params T[] values) {
return values.Min();
}
public static T Max<T>(params T[] values) {
return values.Max();
}
Let's assume that You have a List<int> intList = new List<int>{1,2,3}
if You want to get a max value You could do
int maxValue = intList.Max();
Linq has a Max function.
If you have an IEnumerable<int>
you can call this directly, but if you require these in separate parameters you could create a function like this:
using System.Linq;
...
static int Max(params int[] numbers)
{
return numbers.Max();
}
Then you could call it like this: max(1, 6, 2)
, it allows for an arbitrary number of parameters.
If, for whatever reason (e.g. Space Engineers API), System.array has no definition for Max nor do you have access to Enumerable, a solution for Max of n values is:
public int Max(int[] values) {
if(values.Length < 1) {
return 0;
}
if(values.Length < 2) {
return values[0];
}
if(values.Length < 3) {
return Math.Max(values[0], values[1]);
}
int runningMax = values[0];
for(int i=1; i<values.Length - 1; i++) {
runningMax = Math.Max(runningMax, values[i]);
}
return runningMax;
}
This function takes an array of integers. (I completely understand @Jon Skeet's complaint about sending arrays.)
It's probably a bit overkill.
public static int GetMax(int[] array) // must be a array of ints
{
int current_greatest_value = array[0]; // initializes it
for (int i = 1; i <= array.Length; i++)
{
// compare current number against next number
if (i+1 <= array.Length-1) // prevent "index outside bounds of array" error below with array[i+1]
{
// array[i+1] exists
if (array[i] < array[i+1] || array[i] <= current_greatest_value)
{
// current val is less than next, and less than the current greatest val, so go to next iteration
continue;
}
} else
{
// array[i+1] doesn't exist, we are at the last element
if (array[i] > current_greatest_value)
{
// current iteration val is greater than current_greatest_value
current_greatest_value = array[i];
}
break; // next for loop i index will be invalid
}
// if it gets here, current val is greater than next, so for now assign that value to greatest_value
current_greatest_value = array[i];
}
return current_greatest_value;
}
Then call the function :
int highest_val = GetMax (new[] { 1,6,2,72727275,2323});
// highest_val = 72727275
You could use Enumerable.Max
:
new [] { 1, 2, 3 }.Max();
Maximum element value in priceValues[] is maxPriceValues :
double[] priceValues = new double[3];
priceValues [0] = 1;
priceValues [1] = 2;
priceValues [2] = 3;
double maxPriceValues = priceValues.Max();
off topic but here is the formula for middle value.. just in case someone is looking for it
Math.Min(Math.Min(Math.Max(x,y), Math.Max(y,z)), Math.Max(x,z));
You could try this code:
private float GetBrightestColor(float r, float g, float b) {
if (r > g && r > b) {
return r;
} else if (g > r && g > b) {
return g;
} else if (b > r && b > g) {
return b;
}
}
