Coding an arithmetic formula in ABAP

Former Member — Fri, 23 May 2008 07:38:26 GMT

hi,

I have coded the below formula in ABAP, but when i try to excute it it gives an error

"Incomplete aritmetic expression. ")" missing at end of statement.

v_diearea = v_length * v_width.

v_gdpw = ( 3.1414 / 4 ) * ( ( v_wafer_size ) ** 2 ) *

( 1 - ( ( SQRT ( 8 * ( v_diearea ) ) ) /

( v_wafer_size ) ) ) / ( v_diearea ).

Please let me know what si wrong in the above expression.

Hi ,

it seems not to be a parenthesis problem

1. Use '3.1414' instead of 3.1414

2. Use SQRT( instead of SQRT ( -

> No space between SQRT and parenthesis

The following code should work:

v_diearea = v_length * v_width.

v_gdpw = ( '3.1414' / 4 ) * ( ( v_wafer_size ) ** 2 ) *
( 1 - ( ( SQRT( 8 * ( v_diearea ) ) ) /
( v_wafer_size ) ) ) / ( v_diearea ).
