====== IfError(expression1, expression2) ======
Category:  Logical function

\\ 
=====Description=====
This function returns the result of //expression2// if the result of //expression1// is an error.  Otherwise, it returns the result of //expression1//.

\\ 
=====Use cases=====
This function can be used as an error handler in cases where an expression could potentially return an error.  In such a case, the return value from //expression2// acts as a "safety net" so the process can continue.

\\ 
=====Arguments=====
^Argument^Type^Description^
|expression1|Expression|Any expression that could potentially result in an error.|
|expression2|Expression|Any expression.|
**Return value type:** Any (The data type of the return value of //expression1// or //expression2//.)

\\ 
=====Remarks=====
If both //expression1// and //expression2// return errors, the error message from //expression2// is returned.

\\ 
=====Examples=====

  iferror( 1/0, 'Inifity' ) //Returns 'Infinity'

  iferror( 1+0, 'Infinity' ) //Returns 1

  iferror( 1/0, sqrt('the') ) //Returns '#The argument must be a positive number' (the error from expression2)
