Agreed.  But, there are standard extensions.

There is an international standard about many of the special math functions:
  ISO/IEC 24747 Special Math

I believe that this 
  http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1292.pdf
  Extensions to the C Library, to Support Mathematical Special Functions
is the "same" as that ISO document

There also is a rationale document
