T function requires a description When the ERROR Value is an argument

2. Input Cell [ A1 ] "=T(NA())"
3. #N/A
4. Read T Functiuon Help : https://help.libreoffice.org/latest/en-US/text/scalc/01/04060110.html?#t

The number returned depends on the nature of the argument as follows:

For a numeric argument, N returns that number.
For a Boolean argument, N returns 1 (TRUE) or 0 (FALSE).
For a date/time argument, N returns the equivalent date-time serial number.
For a string argument, or a reference to an empty cell, N returns the value 0.
For an argument that represents an error condition, N propagates the error code.
