Third root from a number

Former Member — Mon, 03 Dec 2007 14:58:20 GMT

Hi ABAPers,

I need to calculate the third root in an ABAP-Programm.

(SAP Release 4.6C)

I know of the SQRT function, but that just returns the square root...

--> 1000 = 10 * 10 * 10

The Third root of 1000 is 10...

Does anybody have an idea?

Thanx in advance!

Greetz,

Pieter

good

go through this code which ll give you idea about the square root,

DATA : in TYPE f VALUE 16 ,

out TYPE f .

CALL METHOD cl_foev_builtins=>square_root

EXPORTING

im_number = in

IMPORTING

ex_result = out.

WRITE out .

you can try this same for third root.

reward point if helpful.

thanks

You can try like this:

data: num type i,

<b>num1 type f</b>.

10 ** 3 = 1000

which implies :

num1 = 1 / 3.

1000 ** num1 = 10

Hi Mrutyunjaya!

Thank you for your reply, I found that one as well, but unfortunately this class is not available in Release 4.6C... (and it´s a Square root function, and I need the third root...)

Thanks though!

Thanks Sudhir!

It works: h_float2 = h_float1 ** ( 1 / 3 ).

Hello

DATA :

F1 TYPE F, Number for which third route is required say 1000

F2 TYPE F, "Temp variable

F3 TYPE F. " Third route value i.e. 10

F2 = LOG( F1 ) / 3.

F3 = exp( F2 ).
