uint64_scale_round

Description:


public uint64 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.

Parameters:

val

the number to scale
num

the numerator of the scale ratio
denom

the denominator of the scale ratio

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 uint64_scale, uint64_scale_ceil, uint64_scale_int, uint64_scale_int_round, uint64_scale_int_ceil.
