ASINH

Undoes SINH: for any number, the value that has it as its hyperbolic sine.

Group: Math. Compatible with DAX.

Syntax

ASINH ( <number> )

Parameter	Type	Description
`number`	Number	Any number.

Returns

Number. The number whose hyperbolic sine is the number given.

Remarks

It undoes SINH: ASINH ( SINH ( 1.5 ) ) is 1.5.
Unlike ACOSH and ATANH, it takes any number, negative ones too: ASINH ( -1 ) is -ASINH ( 1 ).
A blank gives BLANK.

Examples
