Note:

You can also set the maximum thread count in ColdFusion Administrator. Click Server Settings > Settings and specify the number of threads in Default Maximum Thread Count For Parallel Functions.

Description

Use this function to calculate the sum of values in an array.

Returns

The sum of values in an array. If the array parameter value is an empty array, returns zero.

Function syntax

arraySum(array [, parallel] [, maxThreadCount])

History

ColdFusion (2021 release): Introduced the following parameters:

parallel
maxThreadCount

ColdFusion (2018 release): Introduced named parameters.

ColdFusion (2016 release) Update 3 - Added ignoreUndefined parameter.

Parameters

Parameter	Description
array	(Required) Name of an array.
ignoreEmpty	(Optional) Boolean (true/false) value denoting whether to ignore empty (Null or "") values in the array while adding the elements. False by default.
parallel	True if you want to enable parallel programming.
maxThreadCount	The number of threads the function can execute. The number of threads must be between 1-50. If the value exceeds 50, there is an exception.

Example

myArray=[921,22,133,40,345,58,-6];

WriteOutput("Sum of values in myArray is:");

WriteOutput(ArraySum(myArray) & "|"); // returns sum of values in myArray

myNewArray=[];

WriteOutput("Sum of values in myNewArray is:");

WriteOutput(ArraySum(myNewArray)); //returns zero since myNewArray is empty

</cfscript>

<cfscript> myArray=[921,22,133,40,345,58,-6]; WriteOutput("Sum of values in myArray is:"); WriteOutput(ArraySum(myArray) & "|"); // returns sum of values in myArray myNewArray=[]; WriteOutput("Sum of values in myNewArray is:"); WriteOutput(ArraySum(myNewArray)); //returns zero since myNewArray is empty </cfscript>

<cfscript>
       myArray=[921,22,133,40,345,58,-6];
       WriteOutput("Sum of values in myArray is:");
       WriteOutput(ArraySum(myArray) & "|"); // returns sum of values in myArray
       myNewArray=[];
       WriteOutput("Sum of values in myNewArray is:");
       WriteOutput(ArraySum(myNewArray)); //returns zero since myNewArray is empty
</cfscript>

Output

Sum of values in myArray is:1513|Sum of values in myNewArray is:0

Example - using the ignoreEmpty parameter

myarray=ArrayNew(1);

myarray=[-23,56,97,javacast("null",""),"",1,23];

sum=arraysum(myarray,true); //ignoreEmpty=true

writeoutput(sum);

</cfscript>

<cfscript> myarray=ArrayNew(1); myarray=[-23,56,97,javacast("null",""),"",1,23]; sum=arraysum(myarray,true); //ignoreEmpty=true writeoutput(sum); </cfscript>

<cfscript>
       myarray=ArrayNew(1);
       myarray=[-23,56,97,javacast("null",""),"",1,23];
       sum=arraysum(myarray,true); //ignoreEmpty=true
       writeoutput(sum);
</cfscript>

Output

154

Using parallelization

for(i=1;i<=100000;i++){

if(i === 4500)

arr[i]=0;

else

arr[i]=i*2;

}

sum= arr.map(function(item){

return item/2;

},true,20).sum(false,true,10)

writeoutput(sum & " ");

sum = arraysum(array=arr,ignoreempty=true,parallel=true,maxthreadcount=10)

writeoutput(sum & " ");

sum1 = arraysum(arr,false,true,10)

writeoutput(sum1 & " ");

</cfscript>

<cfscript> 
 
for(i=1;i<=100000;i++){ 
if(i === 4500) 
arr[i]=0; 
else 
 
arr[i]=i*2; 
} 
 
sum= arr.map(function(item){ 
return item/2; 
},true,20).sum(false,true,10) 
 
writeoutput(sum & "<br>"); 
 
 
sum = arraysum(array=arr,ignoreempty=true,parallel=true,maxthreadcount=10) 
 
writeoutput(sum & "<br>"); 
 
sum1 = arraysum(arr,false,true,10)
