在NumPy中,astype(int)方法会向下取整。如果需要其他舍入方式,可以使用np.round()函数首先进行舍入,然后再转换为整型。 # 使用np.round()进行舍入后转换为整型rounded_int_array=np.round(float_array).astype(int)print("经过舍入后的数组:",rounded_int_array) 1. 2. 3. 3. 序列图分析 在这一部分,我...
为了更好地理解NumPy数组和不同数据类型之间的关系,我们可以使用ER图进行展示。 NUMPY_ARRAYfloat[]valuesINTEGERintvalueFLOATfloatvalueconverts_tocontains 总结 在这篇文章中,我们介绍了如何将NumPy数组中的浮点数转换为整数,包括使用astype()、np.floor()、np.ceil()、np.round()等方法。对于一些简单的浮点数转换...

numpy.round(a, decimals=0, out=None) Parameters: 1. a (array_like):Input array whose elements need rounding. 2. decimals (int, optional):Number of decimal places to round to. Default is 0 (nearest integer). Negative values round to powers of ten. ...

round(np.random.random(), 4) Out[38]: 0.4342 但是,对于排序算法,我们一般使用的是整数。通常是1-100的整数。因此可以使用: np.random.randint() 这里的 int 指的是 integer 整数。 我们试试查看这个函数的帮助文件: help("numpy.random.randint") Help on built-in function randint in numpy.random: ...
