Load the specified `result` with the specified `value`, even if a non‐zero status is returned (truncating fractional digits if necessary). Return 0 on success, `k_OVERFLOW` if `value` is larger than can be represented by `result`, `k_UNDERFLOW` if `value` is smaller than can be represented by `result`, and `k_NOT_INTEGRAL` if `value` is not an integral number (i.e., there is a fractional part). The behavior is undefined unless `isValidNumber(value)` is `true`.
