WebThe floating format with 16 bits of mantissa, 7 bits of exponent, and a sign bit, is stored in the space of a 32-bit long integer. This format gives a factor of 2.5-3 speed up in multiplication (over IEEE) and a speed up of about a factor of 1.3-4.0 for addition. The speed for the multiply is about 35 cycles. The speed for the add is 35-106 cycles. WebConsider: short i = 30000; short j = 10000; short k = 20000; short l = i + j - k; Intuitively, we know that l should be 20000. But if we don't convert to int first, notice that the addition actually overflows a short in the intermediate calculation. Doing all that math as an int prevents this. There's also performance reasons to do this.
