torch. Finfo function

torch.finfo
torch.finfo It's an object , It represents floating point torch.dtype The number property of . This is similar to
numpy.finfo,torch.float32,torch.float64,torch.float16.

A torch.finfo provides the following attributes:

	# The return value is after the number 
    max_neg_value0 = torch.finfo(torch.float16).tiny #6.103515625e-05
    max_neg_value1 = torch.finfo(torch.float16).max  #65504.0
    max_neg_value2 = torch.finfo(torch.float32).max  #3.4028234663852886e+38
    max_neg_value3 = torch.finfo(torch.float64).max  #1.7976931348623157e+308
