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.
