unsigned int
roundUp(
unsigned int value,
unsigned int boundary);Return the least multiple of the specified boundary that is greater than or equal to the specified value, and 0 if 0 == value or the conversion was not successful. The behavior is undefined unless 1 == numBitsSet(boundary). Note that the conversion will succeed if and only if 0 == value % boundary or (1 << sizeInBits(value)) > (value / boundary + 1) * boundary.
least multiple of boundary not less than value, or 0
