问题 I am working with CSV files and Excel often format prices like this: $ 384.642,54 Where the Decimal is 54. I need to round this number to 384.643 (always round up).

问题 I have a question in regard to dealing with small probabilities values in machine learning models. The standard way to avoid underflow problems which results from multiplying small floating-point numbers is to use log(x) instead of x suppose that x=0.50 the log of which is log(x)=-0.301029996 to recover x later on the value of exp(log(x)) != x that is 0.740055574 != 0.50 So, how is using the logarithm is useful to deal with underflow?? 回答1: This has nothing to do with the overflow. In the
