WebThis webpage is a tool to understand IEEE-754 floating point numbers. This is the format in which almost all CPUs represent non-integer numbers. As this format is using base-2, there can be surprising differences in what numbers can be represented easily in decimal and which numbers can be represented in IEEE-754. As an example, try "0.1". WebApr 12, 2024 · 检查输入的数组，确保它们不包含 NaN 或无穷大的值。可以使用 NumPy提供的np.isnan()和np.isinf()函数来检查是否存在NaN 或无穷大的值，然后使用 NumPy提供的np.nan_to_num()函数将 NaN 或无穷大的值替换为 0。：由于输入的数组包含了 NaN 或无穷大的值，导致计算 ROC_AUC 时出错。

WebJan 27, 2024 · Libraries like NumPy and Pandas let you switch data types, which allows you to reduce memory usage. Switching from numpy.float64 (“double-precision” or 64-bit floats) to numpy.float32 (“single-precision” or 32-bit floats) cuts memory usage in half. But it does so at a cost: float32 can only store a much smaller range of numbers, with less precision.
