util_uint64_scale_round

Description:

public uint64 util_uint64_scale_round (uint64 val, uint64 num, uint64 denom)

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.

val	the number to scale
num	the numerator of the scale ratio
denom	the denominator of the scale ratio

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 util_uint64_scale, util_uint64_scale_ceil, util_uint64_scale_int, util_uint64_scale_int_round, util_uint64_scale_int_ceil.
