    "which is the approximate value of π in radians, rounded to 14 decimal places."

    There is no point to say "in radians" because pi here is not a measure, it is just a number

    "π is an irrational number, which can be defined as the ratio of a circle's circumference to its diameter."

    but you define it as a ratio. Actually, mathematically speaking, pi is "transcendental", as it is not even the solution of an algebraic equation with rational coefficients (AFAIK).

    SF Review comments

    (1) Returns. Delete “in radians” (pi is a ratio and has no units).
    (2) Additional details, second bullet point. Insert “an” before “angle”.
    (3) Examples. In 1st example delete “with precision up” and delete “(radians)”. In 2nd example replace “(radians)” with “(cm2)”.

    Steve: All comments handled

    Olivier: About the definition of PI number, definitely PI is transcendental but this is the standard definition used everywhere. I checked other sources as well. So I see no issues in using it.
