optionmaybeispositiveval

optionmaybeispositiveval is a programming predicate designed to evaluate whether an optional numeric value is positive. It operates on an optional value, such as a Maybe or Option type, and yields a boolean result: true when a concrete value exists and is greater than zero, and false otherwise.

Usage of optionmaybeispositiveval appears in data validation, filtering, and processing pipelines where missing data must not be treated as positive. The predicate consolidates two checks—presence of a value and positivity—into a single operation, helping to simplify conditional logic in codebases that use optional types.

Language-agnostic examples include:

Haskell: optionmaybeispositiveval :: (Num a, Ord a) => Maybe a -> Bool; optionmaybeispositiveval (Just x) = x > 0; optionmaybeispositiveval Nothing = False

Rust: fn optionmaybeispositiveval(opt: Option<i32>) -> bool { matches!(opt, Some(v) if v > 0) }

Python: def optionmaybeispositiveval(opt): return opt is not None and opt > 0

Notes: The exact name, spelling, and behavior may vary by codebase; some variants may treat zero as non-positive, while others might define positive as strictly greater than zero. The term optionmaybeispositiveval is a commonly understood pattern for working with optional numeric data, rather than a standard language feature.
