Description
These functions constitute the math library, libm. They are automati‐
cally 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 avail‐
able 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
