<H1>5.1. Built-in Module <CODE>math</CODE></H1>
This module is always available.
It provides access to the mathematical functions defined by the C
standard.
They are:
<DL><DT><B>acos</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>asin</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>atan</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>atan2</B> (<VAR>x</VAR>, <VAR>y</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>ceil</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>cos</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>cosh</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>exp</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>fabs</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>floor</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>fmod</B> (<VAR>x</VAR>, <VAR>y</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>frexp</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>hypot</B> (<VAR>x</VAR>, <VAR>y</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>ldexp</B> (<VAR>x</VAR>, <VAR>y</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>log</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>log10</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>modf</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>pow</B> (<VAR>x</VAR>, <VAR>y</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>sin</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>sinh</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>sqrt</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>tan</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
<DL><DT><B>tanh</B> (<VAR>x</VAR>) -- function of module math<DD>
</DL>
Note that <CODE>frexp</CODE> and <CODE>modf</CODE> have a different call/return
pattern than their C equivalents: they take a single argument and
return a pair of values, rather than returning their second return
value through an `output parameter' (there is no such thing in Python).
<P>
The module also defines two mathematical constants:
<DL><DT><B>pi</B> -- data of module math<DD>
</DL>
<DL><DT><B>e</B> -- data of module math<DD>
</DL>
