This is lmathx, a library for Lua with all C99 mathematical functions. See
	https://en.wikipedia.org/wiki/C_mathematical_functions
	https://en.wikibooks.org/wiki/C_programming/math.h

To build the library and run a simple test, just do make.
If Lua is not installed in /usr/local, tell make:
	make LUA_TOPDIR=/var/tmp/lhf/lua-5.5.0/install

To install the library where Lua can find it, use a variant of these:
	make install
	sudo make install
	sudo make install LIBDIR=/usr/local/lib/lua/5.5

For detailed installation instructions, see
	https://www.tecgraf.puc-rio.br/~lhf/ftp/lua/install.html

For the latest version of this library, see
	https://www.tecgraf.puc-rio.br/~lhf/ftp/lua/#lmathx

mathx library:
abs		cosh		fmod		log		rint
acos		deg		fpclassify	log10		round
acosh		erf		frexp		log1p		scalbn
asin		erfc		gamma		log2		signbit
asinh		exp		hypot		logb		sin
atan		exp2		ilogb		modf		sinh
atan2		expm1		isfinite	nearbyint	sqrt
atanh		fdim		isinf		nextafter	tan
cbrt		floor		isnan		pow		tanh
ceil		fma		isnormal	rad		tgamma
copysign	fmax		ldexp		remainder	trunc
cos		fmin		lgamma		remquo		version

These are in math but not in mathx; they are mostly related to integers:
huge		maxinteger	mininteger	randomseed	type
max		min		random		tointeger	ult

The functions atan and log behave slightly different in math and mathx.
