| You need to use MiddleValues with this function rather than MiddleWords. MiddleWords removes decimal points for non integer values. Let ([ count = WordCount ( valueList ) ; odd = MiddleValues ( valueList ; Truncate (count/2;0) +1 ; 1 ); even = MiddleValues ( valueList ; Truncate(count/2;0) ; 1 ) ]; Case( Mod ( count ; 2 ) ; odd ; (even+ odd) / 2 ) ) |

| Important to note in the description: "ValueList must be sorted in ascending order." I use the revised version that replaces MiddleWords with MiddleValues, and I use one of the other sort functions on this site as the first item in the Let statement to first sort valuelist , so: Let ([ valuelist = SortValues (valuelist; 1); count = WordCount ( valueList ) ; odd = MiddleValues ( valueList ; Truncate (count/2;0) +1 ; 1 ); even = MiddleValues ( valueList ; Truncate(count/2;0) ; 1 ) ]; Case( Mod ( count ; 2 ) ; odd ; (even+ odd) / 2 ) ) |
