ISFUNCTIONS(n)
- is the number
is the numberDescription
- This function is a group of Information Functions that can be used to find out information about a specific.
- The IS FUNCTION is also known as data information functions, data inspection functions or data-testing functions.
- These functions are simple data validation and data type checking functions.
The ISFUNCTIONS are listed below:
ISARRAY(n) ISLEAPYEAR(n) ISBLANK(n) ISERR(n) ISERROR(n) ISLOGICAL(n) ISNA(n) ISNONTEXT(n) ISREF(n) ISTEXT(n) ISPMT(n) ISEMPTY(n) ISNULL(n) ISEVEN(n) ISODD(n) ISPRIME(n)
- where n is value to check with the function.
The 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.
These are the nine worksheet functions used for testing the type of a value or reference.The function displays 1 or 0 depending on the outcome.
ISBLANK V ISERR V ISERROR V ISLOGICAL ISNA ISNONTEXT ISNUMBER ISREF ISTEXT
- ISBLANK
V refers to an empty cell.
- ISERR
Vl refers to any error value except #N/A.
- ISERROR
V refers to any error value
- ISLOGICAL
V refers to a logical value.
- ISNA
V refers to the NaN error value.
- ISNONTEXT
V refers to any item that is not text.
- ISNUMBER
V refers to a number.
- ISREF
V refers to a reference.
- ISTEXT
V refers to text.
