NAME
     intro - introduction to mathematical library functions

DESCRIPTION
     These functions constitute the math library, libm.a. They
     are automatically 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 RI < math.h >.
