util_uint64_scale_int

Description:

public uint64 util_uint64_scale_int (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.

val	guint64 (such as a ClockTime) to scale.
num	numerator of the scale factor.
denom	denominator of the scale factor.

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 truncated. See also util_uint64_scale_int_round, util_uint64_scale_int_ceil, util_uint64_scale, util_uint64_scale_round, util_uint64_scale_ceil.
