binary floating point number
Numeric data type used for the binary saving of numbers with mantissa and exponents or a number saved in this way. The associated
built-in ABAP type
is t. The internal
representation is in accordance with the norm IEEE-754 (double precision) and uses one bit for the sign, 11 bits for the binary exponent, and 52 bits for the mantissa.
Decimal numbers with 17
places can be represented. Due
to the internal representation by binary fractions, not every decimal number in the value range can be represented exactly by a binary floating point number.
