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
