NAME
       intro - introduction to mathematical library functions

DESCRIPTION
       These  functions constitute the math library, libm.  They are automati-
       cally loaded as needed by the Fortran compiler f77(1).  The link editor
       searches  this  library under the "-lm" option.  Declarations for these
       functions may be obtained from the include file <math.h>.
