.SH NAME
intro \- introduction to mathematical library functions
.SH DESCRIPTION
These functions constitute the math library,
.I libm.
They are automatically loaded as needed by the Fortran compiler
.IR f77 (1).
The link editor searches this library under the \*(lq\-lm\*(rq option.
Declarations for these functions may be obtained from the include file
.RI < math.h >.
