Is it guaranteed that division by power of 10 gives accurate result in Floating-point arithmetic standard)?

I found out that 9 * 0.0001 = 0.0009000000000000001, but 9 / 10_000 = 0.0009 Is it guaranteed that when you divide by power of 10 you will receive exact value (by IEEE 754-2019: IEEE Standard for Floa...

strength reduction leading to different outcomes with respect to signaling NaNs

gcc strength-reduces floating-point expressions such as x * 1.0 into the identity function. This is correct if x is a finite or infinite value, but if x is a signaling NaN, x * 1.0 will be a "qui...
