<p><font size=+1><b>DESCRIPTION </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
These functions provide machine-independent access to data in
a particular byte order.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
<i>Beswap2</i>, <i>beswap4</i>, and <i>beswap8</i> return the 2-byte, 4-byte, and 8-byte
big-endian representation of the bytes in <i>val</i>, respectively.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
<i>Beload2</i>, <i>beload4</i>, and <i>beload8</i> return the 2-byte, 4-byte, and 8-byte
big-endian interpretation of the bytes at <i>p</i>, respectively.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
<i>Beieeeftoa32</i>, <i>beieeeftoa64</i>, and <i>beieeeftoa80</i> format the big-endian
4-byte, 8-byte, or 10-byte IEEE floating-point value at <i>f</i> into
the <i>n</i>-byte string buffer <i>a</i>.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
<i>Leswap2</i>, <i>leswap4</i>, etc. are the little-endian equivalents of the
routines just described.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
<i>Ieeeftoa32</i> and <i>ieeeftoa64</i> format a local machine byte-order floating-point
value into the <i>n</i>-byte string buffer <i>a</i>. <i>Ieeeftoa32</i> expects a 32-bit
floating-point value stored in the bits of <i>u</i>. <i>Ieeeftoa64</i> expects
a 64-bit floating-point value whose high 32-bits are in <i>hi</i> and
low 32-bits are in <i>lo</i>.
