got pointer problem when trying with mean function

Hey, all!

I am trying to use mean function from this library: Arduino Playground - HomePage
So, i wanted to find the mean value from the obtained values of SPI reading function after 60 samples is obtained.
this is part of my code where i am using the mean function:

            for(int count = 0; count<60; count++) 
   {
                      uint32_t IRdc =0;
                      uint32_t Reddc =0;
                      uint32_t IRheartsignal;
                      uint32_t Redheartsignal;

                      IRheartsignal = AFE4490Read(LED1VAL); //SPI reading register function
                      Redheartsignal = AFE4490Read(LED2VAL); //SPI reading register function
                     
                     IRdc = mean ((IRheartsignal, count),DEC);
                     Reddc = mean ((Redheartsignal, count), DEC);
     }

I just follow the use of mean function like on the example on the link : Arduino Playground - HomePage.
but when I compile it, i got this error:

bloodsaturation.ino: In function 'void setup()':
bloodsaturation:102: error: call of overloaded 'mean(int&, int)' is ambiguous
bloodsaturation.ino:24: note: candidates are: uint32_t mean(int*, int)
bloodsaturation.ino:32: note: uint32_t mean(uint32_t*, int)
bloodsaturation:103: error: call of overloaded 'mean(int&, int)' is ambiguous
bloodsaturation.ino:24: note: candidates are: uint32_t mean(int*, int)
bloodsaturation.ino:32: note: uint32_t mean(uint32_t*, int)

I checked again the source code, and it seems it provides mean function in several type (unsigned long, float, long, etc)
So, i think this cause an ambiguous when compiling.

Can someone please help me how is the correct way to use mean function?

IRdc = mean ((IRheartsignal, count),DEC);

What's that?

Mean

Format: average = mean(array, slice_count);

Calculates the mean average of the values in array. slice_count is the number of entries in the array.

array!
Well, yeah! i should tried it that way...
Thanks!

i feel idiot...

OK, let me rephrase.
What do you expect this IRdc = mean ((IRheartsignal, count),DEC); to do, and why doesn't it look anything like the example given in the playground?
What does "DEC" mean, in this context?

(If you want an arithmetic mean, just sum 'n' samples and divide by 'n'.
No library required)
