simple question for everybody: I have an external file containing a double-precision floating point number in IEEE 754 standard.
I read the file in binary mode, obtain the number as a byte sequence and want to convert it in a platform-independent manner into an ABAP type f value.
My simplistic approach to mask the byte field with a type F field-symbol doesn't work platform-independently.
Can anybody help?
Thanks and regards,
