Doh!
Someone already thought of this

Quote: "FastMath is a Delphi math library that is optimized for fast 
performance (sometimes at the cost of not performing error checking or 
losing a little accuracy). It uses hand-optimized assembly code to 
achieve much better performance then the equivalent functions provided 
by the Delphi RTL."

Whether it ports over to fpc, I don't know
