+/**
+  The Fl_Value_Input widget displays a numeric value.
+  The user can click in the text field and edit it - there is in
+  fact a hidden Fl_Input widget with
+  type(FL_FLOAT_INPUT) or type(FL_INT_INPUT) in
+  there - and when they hit return or tab the value updates to
+  what they typed and the callback is done.
+  
+  <P>If step() is non-zero and integral, then the range of numbers
+  is limited to integers instead of floating point numbers. As
+  well as displaying the value as an integer, typed input is also
+  limited to integer values, even if the hidden Fl_Input widget
+  is of type(FL_FLOAT_INPUT).</P>
+  
+  <P>If step() is non-zero, the user can also drag the
+  mouse across the object and thus slide the value. The left
+  button moves one step() per pixel, the middle by 10
+  * step(), and the right button by 100 * step(). It
+  is therefore impossible to select text by dragging across it,
+  although clicking can still move the insertion cursor.</P>
+  
+  <P>If step() is non-zero and integral, then the range
+  of numbers are limited to integers instead of floating point
+  values.
