Why does Math.round(0.49999999999999994) return 1?
... // 3fdfffffffffffff
print(a+b); // 3ff0000000000000
print(1.0); // 3ff0000000000000
}
This is because 0.49999999999999994 has a smaller exponent than 0.5, so when they're added, its mantissa is shifted, and the ULP gets bigger.

The value p should be within [0,1]. This essentially shifts the sgn() function's symmetrical output {-1,0,1} to lean toward one side, partitioning the data samples into two unequally-sized bins (fractions p and 1-p of ...

Why can't (or doesn't) the compiler optimize a predictable addition loop into a multiplication?
... invalid optimisations (for example, a couple of years ago, I had an ICC (11.0, iirc) use signed-32-bit-int-to-double conversion in 1.0/n where n was an unsigned int. Was about twice as fast as gcc's output. But wrong, a lot of values were larger than 2^31, oops.).
