Function

Gst-1.0 ▶ Gst ▶ util_uint64_scale_ceil

  • Scale val by the rational number num / denom, avoiding overflows and underflows and without loss of precision.

    This function can potentially be very slow if val and num are both greater than G_MAXUINT32.

    Parameters

    • val: number

      the number to scale

    • num: number

      the numerator of the scale ratio

    • denom: number

      the denominator of the scale ratio

    Returns number

    val * num / denom. In the case of an overflow, this function returns G_MAXUINT64. If the result is not exactly representable as an integer, it is rounded up.
