<U>DESCRIPTION</U></H4>
where the argument within the parentheses may be an expression.
<P>Value converters perform arithmetic translation from units of one kind
to units of another. The result can then be a term in a further expression. <BR>
<BR>
<BR><TT><B>int</B>(x) returns the integer
part of x.</TT>
<BR><TT><B>frac</B>(x) returns the fractional part
of x.<BR>
<B>dbamp</B>(x) returns the decibel equivalent of the
raw amplitude x.<BR>
<B>i</B>(x) returns an Init-type
equivalent of the argument (k-rate)<BR>
<B>abs</B>(x) returns the absolute value
of x.<BR>
<B>exp</B>(x) returns e raised to the xth
power.</TT>
<BR><TT><B>log</B>(x) returns the natural
log of x (x positive only).<BR>
<B>sqrt</B>(x) returns the square root of x (x
non-negative).<BR>
<B>sin</B>(x) returns the sine of x (x in
radians).</TT>
<BR><TT><B>cos</B>(x) returns the cosine
of x (x in radians).</TT>
<BR><TT><B>ampdb</B>(x) returns the amplitude equivalent
of the decibel value x. Thus</TT>
<BR><TT>
60 db gives 1000,</TT>
<BR><TT>
66 db gives 2000,</TT>
<BR><TT>
72 db gives 4000,</TT>
<BR><TT>
78 db gives 8000,</TT>
<BR><TT>
84 db gives 16000 and</TT>
<BR><TT>
90 db gives 32000.</TT><BR>
<BR>
<P>Note that for <B>log, sqrt</B>, and <B>ftlen</B> the argument value
is restricted. Note also that <B>ftlen</B> will always return a power-of-2
value, i.e. the function table guard point (<A HREF="../NumScore/f-stat.html">see
F statement</A>) is not included. <BR>
