uint64_scale_int_round
Description:
public uint64 uint64_scale_int_round (uint64 val, int num, int denom)
Scale val by the rational number num / denom, avoiding overflows and underflows and without loss
of precision.
num must be non-negative and denom must be positive.
Parameters:
| val |
guint64 (such as a ClockTime) to scale.
|
| num |
numerator of the scale factor.
|
| denom |
denominator of the scale factor.
|
Returns:
|
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 to the nearest integer (half-way cases are rounded up). See also
