N

Returns the numeric value.


Syntax:

N(value)

returns the numeric value of value if possible. It returns the logical values TRUE and FALSE as 1 and 0 respectively.
N() is not intended to convert text to a number - use the VALUE() function instead.


Example:

N(123)

returns 123, because 123 is (already) a number.

N(TRUE)

returns 1.

N(A3)

where A3 contains FALSE, returns 0.

Information functions


Issues:

N() in Calc will convert text to a number, but in Excel it will not. The ODFF standard deliberately does not specify a behaviour. Use VALUE() to convert from text to number.
