If the magnitude is too large to represent as a <code>float</code>, we say the operation overflows; the result is then an infinity of appropriate sign. If the magnitude is too small to represent as a <code>float</code>, we say the operation underflows; the result is then a zero of appropriate sign. </ul><a name="68095"></a>The Java Virtual Machine requires support of gradual underflow as defined by IEEE 754. Despite the fact that overflow, underflow, or loss of precision may occur, execution of an <i>fmul</i> instruction never throws a runtime exception.<p><hr><!-- This inserts footnotes--><p><a href="VMSpecTOC.doc.html">Contents</a> | <a href="Instructions2.doc62.html">Prev</a> | <a href="Instructions2.doc64.html">Next</a> | <a href="Mnemonics.doc.html">Index</a><p><font size=-1>Java Virtual Machine Specification (HTML generated by dkramer on February 25, 1997)<br><i><a href="Copyright.doc.html">Copyright © 1996 Sun Microsystems, Inc.</a>All rights reserved</i><br>Please send any comments or corrections to <a href="mailto:doug.kramer@sun.com">doug.kramer@sun.com</a></font></body></html>⌨️ 快捷键说明
