The positive infinity in Javascript is a number that is constant and represents a value that is the highest available. It can be generated using a self-made function or by an arithmetic operation.
Note: JavaScript shows the POSITIVE_INFINITY value as Infinity.
Positive Infinity: It is different from mathematical infinity in the following ways.
- If we divide any positive number by positive infinity, we will get a positive 0
- If we divide any negative number by positive infinity, we will get negative 0.
- 0 multiplied by positive infinity is NaN
- NaN multiplied by positive infinity is NaN
- We get negative infinity when we divide positive infinity by any negative number (except negative infinity)
- We get positive infinity when we divide positive infinity by any positive number (except positive infinity)
- Positive infinity divided by either positive or negative infinity is NaN
Syntax:Â
Number.POSITIVE_INFINITY
