+<h3>FREXP(3) Linux Programmer's Manual FREXP(3)
+</h3>
+
+<h3>NAME
+</h3> frexp - convert floating-point number to fractional and
+ integral components
+
+<h3>SYNOPSIS
+</h3> #include &lt;math.h&gt;
+
+ double frexp(double x, int *exp);
+
+<h3>DESCRIPTION
+</h3> The frexp() function is used to split the number x into a
+ normalized fraction and an exponent which is stored in
+ exp.
+
+<h3>RETURN VALUE
+</h3> The frexp() function returns the normalized fraction. 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.
