is_numeric function in ABAP

Question

I'm currently trying to find a Standard-FM or Class or inbuilt-Function, that can perform a "simple" numeric check. Currently i just do IF val CO '0123456789.,+-'. But thats not really nice.

For example 12,45.64,47-18 would pass this check, while it's clearly not a number. It should return "not a number" in this case. Also what about some other formats, like 123.345,786e13. That is a valid number and should convert.

Same with different formats (. for grouping or , for example, should depent on the environment or User i think). Is there a good way for checking this? It feels to be such a basic task, but i just cant find anything, not even with googling.

Regex could help you, but you have to specify exactly what you need. I.e. thousand separator dot? decimal coma? etc. — József Szikszai

@JózsefSzikszai Best case would be if that information is extracted from the user profile, but dot as thousand separator and comma as decimal would fit 99 % of our use cases — Schesam

Where does this number come from, what rule do you want concerning the language environment? There could be some specific rules if your number is a currency amount, or if you want to check maximum values, maximum number of digits in the fraction, minus before or after, exponent, etc. For "Dynpro" input (SAP GUI screens), there's the official (released) function module RS_CONV_EX_2_IN. — Sandra Rossi

I just wanna check if a specific input is numeric. It can come from a csv/excel-Upload, a Database, User-Input in Parameters or somewhere else. — Schesam

Why not simply assign the value to a variable of type decfloat34? If the input is not a number, the exception CONVT_NO_NUMBER will be raised — rz96789
