Функция ТИП.ОШИБКИ

Returns a number representing a specific Error type, or the error value #N/A, if there is no error.

ERROR.TYPE(Error_value)

Error_value – required argument. The error value or a reference to a cell, whose value needs to be processed.

Значение ошибки	Returns
#NULL! (Err:521)	1
#DIV/0! (Err:532)	2
#VALUE! (Err:519)	3
#REF! (Err:524)	4
#NAME? (Err:525)	5
#NUM! (Err:503)	6
#N/A (Err:32767)	7
Anything else	#Н/Д

Простое использование

=ТИП.ОШИБКИ(#Н/Д)

Returns 7, because 7 is the index number of the error value #N/A.

=ТИП.ОШИБКИ(A3)

If A3 contains an expression equivalent to the division by zero, the function returns 2, because 2 is the index number of the error value #DIV/0!

More advanced way

If in division A1 by A2, A2 can turn to zero, you can handle the situation as follows:

=IF(ISERROR(A1/A2);IF(ERROR.TYPE(A1/A2)=2;"the denominator can't be equal to zero");A1/A2)

The ISERROR function returns TRUE or FALSE depending on whether there is an error or not. If the error takes place, the function IF addresses to the second argument, if there is no error, it returns the result of the division. The second argument checks the index number representing the specific Error type, and if it is equal to 2, it returns the specified text "the denominator can't be zero" or 0 otherwise. Thus, clear text would signify the division by zero, the result of the division would appear when the division is successful, or if there is, for example, an error of another type, zero would be returned.
