Original array: [-0.7 -1.5 -1.7 0.3 1.5 1.8 2. ] Round elements of the array to the nearest integer: [-1. -2. -2. 0. 2. 2. 2.] Explanation:numpy.rint function is used to round elements of the array to the neares
vocab : :class:`~numpy_ml.preprocessing.nlp.Vocabulary` instance or None If not None, only the words in `vocab` will be used to construct the language model; all out-of-vocabulary words will either be mappend to ``<unk>`` (if ``self.unk = True``) or removed (if ``self.unk =...
The round() function can also be used to round negative values in an array. Here, when the decimal part of a number is greater than to 0.5, it rounds up to the nearest integer. If the decimal part is less than 0.5, the function rounds down. In this case, we don't specify the ...
3、public static int[] copyOfRange(int[] original,int from, int to):根据original数组,复制一个新数组, 从original[from]开始复制,如果to超过original的length,那么复制到original最后一个, 如果to在original的合理下标范围内,那么[from,to) 4、public static boolean equals(int[] a,int[] a2):比较两个...
