Name
       intro - introduction to mathematical library functions

Description
       These  functions  constitute  the  math	library,  libm.   They	are automatically loaded as needed by the FORTRAN compiler The link editor
       searches this library under the "-lm" option.  Declarations for these functions may be obtained from the include  file  <math.h>.   On  VAX
       machines,  the  GFLOAT  version of libm is used when you use the command with the lcg option.  Note that you must use the GFLOAT version of
       libm with modules compiled using the with the -Mg option.

       Also on VAX machines, note that neither the compiler nor the linker can detect when mixed double floating point types  are  used,  and  the
       program may produce erroneous results if this occurs.

System V Compatibility
       This  library  contains	System V compatibility features that are available to general ULTRIX programs.	For a discussion of how these fea-
       tures are documented, and how to specify that the System V environment is to be used in compiling and linking your programs, see
