<p>
This is a convenience constructor that allows creation of a numeric 
<a class="link" href="GtkSpinButton.html" title="GtkSpinButton"><span class="type">GtkSpinButton</span></a> without manually creating an adjustment. The value is 
initially set to the minimum value and a page increment of 10 * <em class="parameter"><code>step</code></em>
is the default. The precision of the spin button is equivalent to the 
precision of <em class="parameter"><code>step</code></em>. 
</p>
<p>
Note that the way in which the precision is derived works best if <em class="parameter"><code>step</code></em> 
is a power of ten. If the resulting precision is not suitable for your 
needs, use <a class="link" href="GtkSpinButton.html#gtk-spin-button-set-digits"><code class="function">gtk_spin_button_set_digits()</code></a> to correct it.</p>
