# SIGN

The SIGN function is used to determine the sign of a number. It returns 1 if the number is positive, -1 if the number is negative, and 0 if the number is zero.

=SIGN(`number`)

When you need a quick assessment of whether a number is positive, negative, or zero in Excel, the SIGN function is your go-to option. It simplifies the task of evaluating the sign of a numeric value, providing a clear indication of its positivity or negativity with numerical precision. This functionality proves handy in various scenarios, such as analyzing financial data or sorting numbers based on their sign.

## Examples ðŸ”—

If you have a cell containing the number 27, you can use the SIGN function to determine its sign as follows:

=SIGN(A1)

For a negative number like -15 in cell B1, you can also apply the SIGN function to ascertain its sign:

=SIGN(B1)

If you wish to evaluate the sign of a calculated result, say 0.005 from a formula, you can still employ the SIGN function:

=SIGN(YOUR_FORMULA_RESULT)
