INTRO(3M) UNIX Programmer's Manual INTRO(3M) NAME intro - introduction to mathematical library functions DESCRIPTION These functions constitute the math library, _l_i_b_m. They are automatically loaded as needed by the Fortran compiler _f_7_7(1). The link editor searches this library under the -lm option. Declarations for these functions may be obtained from the include file <_m_a_t_h._h>.
