# The Excel function: LOGNORM.DIST

## Syntax

LOGNORM.DIST(x,mean,standard_dev,cumulative)

The LOGNORM.DIST function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

**X**Required. The value at which to evaluate the function.**Mean**Required. The mean of ln(x).**Standard_dev**Required. The standard deviation of ln(x).**Cumulative**Required. A logical value that determines the form of the function. If cumulative is TRUE, LOGNORM.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.
