How to check whether a string includes only numeric characters.

[Former Member]

Hi,

I need to write a function module which judges whether a string includes only numeric characters.

Import: a string

Export:

- True: If this is a numeric string

- False: The string includes non-numeric characters

Thanks in advance!

its as simple as checking

xx co ( 1234567890 )

DATA: text(10).
text = '0123456789'.

  IF string CA text.
write:/ 'numeric'.
else. 
write:/ non-numeric'.
endif.

CA is incorrect, it needs ot be CO

DATA: text(10).
text = '0123456789'.
 
  IF string CA text.   <----------  should be CO instead of  CA
write:/ 'numeric'.
else. 
write:/ non-numeric'.
endif.

Also you can check FM: NUMERIC_CHECK.

Hi ,

Try using this FM.

data in_string type string.

data out_string type string.

data h_type type string.

CALL FUNCTION 'NUMERIC_CHECK'

EXPORTING

string_in = in

IMPORTING

STRING_OUT = out

HTYPE = h_type.

if h_type = 'CHAR'.

WRITE:/ 'Not Numeric'.

else.

write:/ 'Numeric'.

ENDIF.

Hope this will be useful for you.

Regards,
