Note that this will not work with whole numbers, or numbers that are already decimals.

Here's a modified version that works for whole numbers (might work with decimals too): /* Determines format of fraction and if a valid fraction based on passed text string. From: https://www.briandunning.com/cf/1359 Required Functions: FractionNumerator FractionDenominator © Brett Buchmiller 10-2011 Portions © Inveniem 2019 (Whole Number Handling) */ If( IsEmpty(input) or (Position(input; "/"; 1; 1) < 1) or FractionDenominator(input) = 0; /* Conditional */ If( /* Conditional */ GetAsNumber(input) = input; /* When: True (input is already a number) */ "Whole"; /* When: False (input is neither fraction nor a number) */ "Invalid" ); If( /* Conditional */ Position(input; " "; 1; 1) > 0; /* When: True */ "Mixed"; /* When: False */ If( /* Conditional */ FractionNumerator(input) > FractionDenominator(input); /* When: True */ "Improper"; /* When: False */ "Proper" ) ) )
