# ASINH

Returns the inverse hyperbolic sine of a number. The inverse hyperbolic sine is the value whose hyperbolic sine is number, so ASINH(SINH(number)) equals number.

## Syntax

ASINH(number)


### Parameters

Term Definition
number Any real number.

## Return value

Returns the inverse hyperbolic sine of a number.

## Remarks

This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
