Function

Gst-1.0Gstutil_simplify_fractionSince 1.24

  • Calculates the simpler representation of numerator and denominator and update both values with the resulting simplified fraction.

    Simplify a fraction using a simple continued fraction decomposition. The idea here is to convert fractions such as 333333/10000000 to 1/30 using 32 bit arithmetic only. The algorithm is not perfect and relies upon two arbitrary parameters to remove non-significative terms from the simple continued fraction decomposition. Using 8 and 333 for n_terms and threshold respectively seems to give nice results.

    Parameters

    • numerator: number

      First value as gint

    • denominator: number

      Second value as gint

    • n_terms: number

      non-significative terms (typical value: 8)

    • threshold: number

      threshold (typical value: 333)

    Returns void
