# Sign (Positive/Negative)

## Sign/Polarity of Numbers

Tool for evaluating the sign of a number (its polarity) or a list of relative numbers and possibly change the sign, find absolute value, sort or separate values greater than or less than 0.

### How to determine the sign of a number?

Plus (+) and minus (-) signs are used to represent the polarity of a number, e.g. its position relative to the value 0. A negative number begins with the symbol - and a positive number by + but this is generally omitted (absent from representations of positive numbers).

Example: +123 is simply written 123

Example: 0 is considered positive by default

### What is the absolute value?

The absolute value of a number is the value of the number regardless of the sign (ie always positive).

Example: The absolute value of -4 is 4

### Is Zero positive or negative?

Everything depends on the meaning of the words positive and negative, in the strict sense, zero has no sign, it will be considered neither positive nor negative. In practice it is considered to be both positive and negative.
