How computer computes Negative(-) and Positive(+) Infinity?

Question

We all know, if we divide (1.0/0.0) we will get +Infinity and if we divide (-1.0/0.0) we will get -Infinity! I want to know How computers calculate this value, internally ??

PS: I wondering why I didn't find any question regarding this in any of StackExchange community!

In IEEE 754, the results of the division you show will depend on the sign of the zero ! — Yves Daoust, Sep 05 '19 at 13:28
@YvesDaoust This is an important detail to point out. Thank you. — Zéychin, Sep 06 '19 at 15:18

Short answer: It will detect that you divide by 0 and not do the actual division.
