Fixed point isn't any better than floating point.

If anything errors in floating point numbers are graceful and give you a lot of leeway before they become catastrophic. Fixed point works until you hit 2(n-1) bits then probably breaks unexpectedly. Where n is the last exponent you have seen in business.

Fixed point libraries tend to be better because good ones can cleanly identify when they're unable to continue and often tell you why.

Floating point libraries can't even do this.
