This is a bit more consistent with the naming of the other header files (openlibm_complex.h and openlibm_fenv.h). Re-add an openlibm.h header that includes all of the public headers as a shorthand. Fix up all of the source files to include <openlibm_math.h> instead of <openlibm.h>. While there, fix ordering of the includes.

/* cexpl()
|
|
*
|

|
|
* SYNOPSIS:
|
|
*
|
|
* long double complex cexpl();
|
|
* long double complex z, w;
|
|
*
|
|
* w = cexpl( z );

|
*
|
|
* DESCRIPTION:
|
|
*
|
|
* Returns the exponential of the complex argument z
|
|
* into the complex result w.
|
|
*
|
|
* If
|
|
* z = x + iy,
|
|
* r = exp(x),
|
|
*
|
|
* then
|
|
*
|
|
* w = r cos y + i r sin y.
|
|
*
|
|
*
|
|
* ACCURACY:
|
|
*
|
|
* Relative error:
|
|
* arithmetic domain # trials peak rms
