If it looks like a duck and quacks like a duck, it probably is a duck.

An integer is a whole number.
FIXED BINARY (15) and FIXED BINARY(15,0)
are both attributes describing a whole number,
that is, an integer.

"PL/I doesn't have integers."

Sorry Shmuel, youre incorrect.

FIXED BINARY (15,0) is a 2 byte integer and FIXED BINARY (31,0) is a 4 byte
integer.

"The ratiio 4/3 is FIXED BIN,"

No, its FIXED DECIMAL (1,0)...

Beware!  Than might left-associate as:
    volume = ( 4/3 ) * 3.14159 * radius**3
... and the quotient of integers, 4/3, is 1.
