Math Libraries - Sun Microsystems SunSoft Pascal 4.0 User Manual

Math Libraries

This chapter describes how to use the libm and libsunmath functions in
Pascal programs. The math libraries are always accessible from a Pascal
program because the Pascal compiler driver pc calls ld, the linker and loader,
with the -lsunmath -lm options. If you compile Pascal program with the -v
option, it prints the command-line used to call each of the compilation passes.
For convenience, Pascal supports special Pascal header files, math_p.h and
sunmath_p.h, which contain prototypes of math functions, procedures, and
some useful constants. The math_p.h file refers to sunmath_p.h by an
#include directive.
This chapter contains the following sections:
Contents of the Math Libraries
libm Functions
IEEE Support Functions
SPARC Libraries
Arithmetic Exceptions
Math Library Exception-Handling Function: matherr()
libsunmath Support for IEEE Modes and Exceptions
