Hello All!

I need a example for use mathematics function EXP for calcule exponential.

I have 2 variables type F. How can i do that?

Hello

Like this:


DATA: F1 TYPE F, F2 TYPE F.

F2 = 123.

F1 = EXP( F2 ).

WRITE: F1, F2.

Hi Rodrigo,

Try this :-

DATA: I1 TYPE I, I2 TYPE I, I3 TYPE I, 
      F1 TYPE F, F2 TYPE F, 
      WORD1(10), WORD2(20), 
      XSTR TYPE XSTRING. 
... 
F1 = ( I1 + EXP( F2 ) ) * I2 / SIN( 3 - I3 ). 
COMPUTE F1 = SQRT( SQRT( ( I1 + I2 ) * I3 ) + F2 ). 
I1 = STRLEN( WORD1 ) + STRLEN( WORD2 ). 
I2 = STRLEN( XSTR ).

Thank's, but i saw that this function not solve my problem.

This is a example:

i have 2 variables:

var1 = 4.

var2 = 3.

So, i need to result about exponential of this data. I need result = 64.

Another example:

var1 = 3.

var2 = 2.

result should be 9.

please, help me!

Hello

A small snippet for this:


DATA: P1 TYPE P, P2 TYPE P, RESULT TYPE P.

P1 = 4.
P2 = 3.

RESULT = 1.
DO P2 TIMES.
  RESULT = RESULT * P1.
ENDDO.

WRITE: RESULT.

C'mon Dzed,

Its not that complicated

DATA:
      v_num1 TYPE i VALUE '4',
      v_num2 TYPE i VALUE '3',
      v_res TYPE i.

v_res = v_num1 ** v_num2.

WRITE v_res.

Cheers,

Suhas

Hi Rodrigo,

Use power expression "x*y" means that x is multiplied by itself y times, where y is a natural numebr. xy = exp(ylog(x)) for any value of y.
