How to say the value. Machine shops usually speak in terms of thousandths of an inch. Because of this when we describe the value to someone else we will read it a little different than you might expect. As noted above, if we give the example of 7.489136″ a machinist would describe the value as 7 inch, 489 thousandths, 1 tenth, 36 millionths. IEEE 754 Machine Numbers and Machine Arithmetic "battle over gradual underflow" Machine numbers consist of the following: = ± (.1 These are the standard machine numbers discussed in class used to represent nonzero values. = ± (.0 This allows to represent 0 with a sign (in case of underflow the sign is preserved, see example below).
