WebNaN的出現可能是因為wid值非常小（接近零），盡管我認為這不太可能-我不記得曾經見過這種情況。或NaN可能來自您的數據-我已經看過很多次了，您的代碼看起來非常專注於處理數據。因此，請首先驗證您的數據xCore和yCore不包含NaN。 In floating-point calculations, NaN is not the same as infinity, although both are typically handled as special cases in floating-point representations of real numbers as well as in floating-point operations. An invalid operation is also not the same as an arithmetic overflow (which would return an infinity or the largest finite number in magnitude) or an arithmetic underflow (which would return the smallest normal number in magnitude, a subnormal number, or zero). bk precision 1823a
