should be (fl+ x ...) and (fl* x ...) respectively.

Fixed.

Regarding flabsdiff, you refer to C99 fdim, but unlike every other useful suggestion offered, fdim does not appear to be useful here (ie. fdim(-10.0,10.0) => 0).

This was a brain fart; I was thinking that fdim was the absolute difference

rather than the positive difference. I now have both flabsdiff without a C99

reference, and fposdiff with a reference to fdim.

flsgn refers to "flcopy-sign", which was previously spelled "flcopysign"

Fixed.

fllog1+ , "Equivalent to (fllog (fl+ 1 x)), but ..." fl+ requires flonum arguments, but 1 is an exact integer. Change to 1.0, or (flonum 1).

Fixed.

..except that atan2 does not return the same thing as atan(y/x).

I thought that was the whole point of atan2.

http://en.cppreference.com/w/cpp/numeric/math/atan2 says

"Computes the arc tangent of y/x using the signs of arguments

to determine the correct quadrant."

Also, the spec suggests that y is the second argument to flatan, but "y" is conventionally the first argument to atan2.

Fixed.
