# How to get the count, sum, average, maximum, and minimum of numbers in an array.

Japanese version.

## Steps

For any calculation, an array of numbers is prepared first.

### count

Use the length function in the expression.

`length(variables('array'))`

### sum

A variable for the total is provided with an initial value of 0.

The contents of the array are repeated with "Apply to each".

The "Current item" is added by "Increment variable".

When the iteration is completed, the total value is obtained.

### average

Divide the aforementioned total by the number of cases. The division is done with the div function.

Also, when averaging integers, the decimal point will be truncated, float function is also used.

`div(float(variables('total')),length(variables('array')))`

### maximum

Use the max function in the expression.

`max(variables('array'))`

### minimum

Use the min function in the expression.

`min(variables('array'))`
