• ISNA(n)
  • Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle n} refers to the NaN error value.
• ISNONTEXT(n)
  • Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle n}  refers to any item that is not text.

  • n refers to a number.
• ISARRAY(n)
• ISLEAPYEAR(n)
• ISPMT(n)
• ISEMPTY(n)

• where Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle n} is value to check with the function.

The Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle n} can be any type like empty cell, Boolean values,text,non text,number,reference-value or name referring to any of these.

• This function will give the result as either TRUE or FALSE according to the $n$ value.
• This function will not convert any numbers from text.
• For e.g. "20" is normally converted as a number 20. But in ISNUMBER("20") will return FALSE, because "20" will not convert in to number.
