Calculation method and processing rules
Use DataView to code according to IEEE754 to distinguish regular numbers, sub-normal numbers, positive and negative zeros, infinity and NaN.
scope of use
Support large-end or small-end byte display; not an arbitrary precision calculator, the NaN decoding reserves the input bit mode, and the text input is parsed by javascript number.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
Support large-end or small-end byte display; not an arbitrary precision calculator, the NaN decoding reserves the input bit mode, and the text input is parsed by javascript number. Please compare the input unit, rounding method, applicable rules and data version first.
