So it looks like you're just asking for a new way to write numbers, right? You want to write out numbers as the literal bit pattern of a 32-bit float.

I feel pretty confident that we'll reject this without a *very* good reason otherwise.

* All of the numbers in your example are *much longer* written that way than in the normal way as integers (where they need only 2-3 characters). I'd like to see examples of numbers which a) require more than 10 characters to write in standard decimal, and b) actually require the precision of those extra digits.
* Float bit patterns are unreadable by humans. I have to do some *work* to decipher 0x42480000 into 50⏨, and the only reason I can do so is because I'm weird and find the minutia of bit patterns interesting to remember.

You mention "high precision line screen/half tone for print for use SVG replace PDF" - what do you mean by this? Why do you need a 32-bit float syntax specifically to achieve this?
