If the argument x is not zero, the normalized fraction is x times a power of two, and is always in the range 1/2 (inclusive) to 1 (exclusive). If x is zero, then the nor- malized fraction is zero and zero is stored in exp. <h3>CONFORMING TO </h3> SVID 3, POSIX, BSD 4.3, ISO 9899 </pre> <hr> <h3>SEE ALSO </h3><p> <a href=ldexp.htmldexp</a>, <a href=modf.htm>modf</a>, <pre> <h3>GNU June 6, 1993 1 </h3> </pre> <P> <hr> <p> <center> <table border=2 width=80%> <tr align=center> <td width=25%> <a href=../index.htm>Top</a> </td><td width=25%> <a href=../master_index.html>Master Index</a> </td><td width=25%> <a href=../SYNTAX/keywords.html>Keywords</a> </td><td width=25%> <a href=../FUNCTIONS/index.htm>Functions</a> </td> </tr> </table> </center> <p> <hr> This manual page was brought to you by <i>mjl_man V-2.0</i>
