FORMAT function with standard string and 1 decimal digit
I have a pivot table and for the calculation of the values i am using a switch statement. For each different row i have a different calculation.
Code of each row is like this:
SWITCH(SELECTEDVALUE(v_raw_data[metric_code]),
"T_01",FORMAT([T_01],SELECTEDVALUE(v_raw_data[value_formatter])),
BLANK())
In the value_formatter i am using the standard string list.
PREDEFINED NUMERIC FORMATS Format Description
| "General Number" | Displays number with no thousand separators. |
| "Currency" | Displays number with thousand separators, if appropriate; displays two digits to the right of the decimal separator. Output is based on system locale settings. |
| "Fixed" | Displays at least one digit to the left and two digits to the right of the decimal separator. |
| "Standard" | Displays number with thousand separators, at least one digit to the left and two digits to the right of the decimal separator. |
| "Percent" | Displays number multiplied by 100 with a percent sign (%) appended immediately to the right; always displays two digits to the right of the decimal separator. |
| "Scientific" | Uses standard scientific notation, providing two significant digits. |
| "Yes/No" | Displays No if number is 0; otherwise, displays Yes. |
| "True/False" | Displays False if number is 0; otherwise, displays True. |
| "On/Off" | Displays Off if number is 0; otherwise, displays On. |
In the way that this works if decimals exist then i always get 2 decimals. Else i have integers. I am giving you also i picture
How can i change it to give me if we have decimals only one. But not all values to have one decimal.
In another way if i have these two function:
1) FORMAT ( 5, "0.#" )
2) FORMAT ( 0.56, "0.#" ) How can i succeed with a result of
1) 5
2) 0.6with the same String format.
Yes that's the idea.
I would suggest you use variables to avoid evaluating the same measure(s) multiple times.
The code I posted earlier was what I was thinking as far as structure:
- Store the measure itself in one variable MeasureValue (T_01, T02 etc).
- Then store the chosen format string in a second variable
- Finally, format the measure using the format string

Hi kyrpav
I don't believe there is any solution involving a single format string that will show integers with no decimal point/places, but otherwise show a decimal point & one decimal place.
I would say the other options are either:
1. Add an additional column to your v_raw_data table that specifies format strings for integers, e.g. add a column v_raw_data[value_formatter_integer].
Then change your DAX expression so that it uses this new column for integers. Something like this (with a bit of re-jigging as well):VAR MetricValue = SWITCH ( SELECTEDVALUE( v_raw_data[metric_code] ), "T_01", [T_01], //... BLANK () ) VAR FormatString = IF ( MetricValue = TRUNC ( MetricValue ), -- integer SELECTEDVALUE ( v_raw_data[value_formatter_integer] ), SELECTEDVALUE ( v_raw_data[value_formatter] ) ) RETURN FORMAT ( MetricValue, FormatString )2. Alternatively, you could do something with calculation group format strings.

I was thinking the same thing if i understand well to do it like
switch(selectedvalue(v_raw_data[metric_code]), "T_02",if(TRUNC([T_02])=[T_02],FORMAT([T_02],SELECTEDVALUE(v_raw_data[value_formatter])),FORMAT([T_02],"##0.0"))but i did not like to run the same function too many times. What you propose to split it also i think is better.
Yes that's the idea.
