Determining number

[Former Member]

Hi,

I would like to know is there any simple code that would able to let me to see whether an input is an integer or is a character. For example, isNumber(0012) would return true and isNumber(CRMD) would return false.

Thanks a lot!

Regards,

Anyi

You can try something like this.

report zrich_0001.


data: value type string.
data: len type i.

value = '12348a'.
len = strlen( value ).

if value+0(len) co '1234567890'.
  write:/ 'This is a numeric value'.
else.
  write:/ 'This is not a numeric value'.
endif.

Function module NUMERIC_CHECK returns NUMC for numeric and CHAR for character inputs.

you can use the function module:

NUMERIC_CHECK:

sample code:

DATA: TYPE LIKE DD01V-DATATYPE.

CALL FUNCTION 'NUMERIC_CHECK'

EXPORTING

STRING_IN = VALUEIN

IMPORTING

STRING_OUT = HFELD

HTYPE = TYPE.

IF TYPE EQ 'NUMC'.

write:/ 'Numeric'.

else.

write:/ 'not numeric'.

ENDIF.

U can even use the logic..

IF linput CA sy-abcde.

write : / 'Non-numberic'.

else.

write : / 'Numeric'.

endif.

This should get you all the data about a field that you require:

REPORT  zz_temp.

DATA:  g_i TYPE i.
DATA:  g_c(20) TYPE c.
DATA   g_type TYPE c.
DATA   g_len TYPE i.


DESCRIBE FIELD g_i TYPE g_type.
WRITE: / g_type.

DESCRIBE FIELD g_c TYPE g_type LENGTH g_len..
WRITE: / g_type, g_len.
