Leading zero before decimal is missing

[metamict]

Hopefully this is the right place for this question.

I have a calculation field that results in either a number or a number (e.g. "1.2" with a less than sign in front of it (e.g., "<1.1").  I have the calculation round the number to 1 decimal place.  The calculation works but the if the result is "0.9", the field only displays ".9".  How can I force the field to show the leading zero on the decimal (e.g., "0.9" instead of ".9")?

I can't use the inspector to format the result as a decimal, because that removes all of the values with a less than sign entirely (i.e., a field that should appear as "<1.1" will be displayed as empty.

So my questions: 1) what is going on here? and 2) what can I do to force filemaker to show the leading zero in a decimal number"

This is Filemaker 16 Advanced.

 

Thank you!

Filemaker removes ALL leading zeros from a number - including the first one:

GetAsNumber ( "0.5" )

returns  .5.

If the result can be either a number or an expression like "<1.1", then you need to set the calculation's result type to Text. And that means you need to format the resulting number yourself, for example by something like:

Int ( result ) & If ( Mod ( result ; 1 ) ; Mod ( result ; 1 ) )

 

Alternatively, you could calculate the number as number only, format the calculation field to display as Decimal, and use another field to show the sign. But that would work well for display only, not for exporting, for example.

Thanks so much for information about both questions.  This is really clarifies things for me.  Very much appreciated!
