Binary floating point number
Numerical data type for binary
saving of numbers with mantissa and exponents/this type of saved number.
The associated predefined ABAP type
is t . The internal
representation is in accordance with the norm IEEE-754 (double
precision) and uses 1 bit for the sign, 11 bits for the binary exponent
and 52 bits for the mantissa. Decimal
numbers with 17 decimal places can
be outputed. 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.
