Thank you very much!

I never used the string(n,s) function. That's useful. Now I know.


String function

    string(n)
       Domain:       -8e+307 to 8e+307 and missing
       Range:        strings
       Description:  returns n converted to a string:
                         string(4)+"F" = "4F"
                         string(1234567) = "1234567"
                         string(12345678) = "1.23e+07"
                         string(.) = "."

    string(n,s)
       Domain n:     -8e+307 to 8e+307 and missing
       Domain s:     strings containing %fmt numeric display format
       Range:        strings
       Description:  returns n converted to a string:
                         string(4,"%9.2f") = "4.00"
                         string(123456789,"%11.0g") = "123456789"
                         string(123456789,"%13.0gc" = "123,456,789"
                         string(0,"%td") = "01jan1960"
                         string(225,"%tq") = "2016q2"
                         string(225,"not a format") = ""
