How do computers store the value Infinity since computers store things in binary?

Question

I noticed that Java and JS have the values Infinity and -Infinity , so I was wondering how do computers store the value Infinity since computers store things in binary?Is there perhaps a specific bit?

Answer 1

"Though it is impossible for a computer to literally represent the value of infinity in memory, the Java "double" and "float" data-type reserves two slots in its address range that are understood by the computer to refer to positive and negative infinity." -Amber D. Walker

Answer 2

Considering that Infinity value is expected in IEEE 754, i think that it is represented as the standard set, with:
Exponent: all 1s
Mantissa: all 0s
Sign bit: 1 if negative, 0 if positive normally
