Introduction:Just now I checked the relevant information on the Internet. IEEE Std 754-2008 has been replaced by IEEE Std 754-2019. This PDF file is free to download only for your study and work.Part of the document is as follows:
5.12.1 External character sequences representing zeros, infinities, and NaNs
The conversions (described in 5.4.2) from supported formats to external character sequences and back that recover the original floating-point representation, shall recover zeros, infinities, and quiet NaNs, as well asnon-zero finite numbers. In particular, signs of zeros and infinities are preserved.
PS:Thank you for your support!
