is_floating_point:检查输入的数据类型是否是浮点型,例如torch.float64, torch.float32, torch.float16和torch.bfloat16,用法如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 torch.is_floating_point(input) is_nonzero:检查输入的单元素张量在类型转换后是否为0,用法如下: ...
一、变量和对象(Variables and objects) 二、数据转换输入(Input with data conversion) 如果在python3中使用int函数,结果总是一个字符串。如果我们想输入一个数字,我们必须把字符串转换成数字。 x=int(input("Input an integer:")) y=float(input("input a float:")) print(x,y) 输入圆的直径并计算其面积...

“0.1” is explained in precise detail below, in the “Representation Error” section. SeeExamples of Floating Point Problemsfor a pleasant summary of how binary floating-point works and the kinds of problems commonly encountered in practice. Also seeThe Perils of Floating Pointfor a more complete...
Return a floating point number constructed from a number or stringx. If the argument is a string, it should contain a decimal number, optionally preceded by a sign, and optionally embedded in whitespace. The optional sign may be'+'or'-'; a'+'sign has no effect on the value produced. ...
