If the decimal point of a decimal is moved one place to the left, and then enlarged by 1000 times, 2012 is obtained. What is the original decimal?
一个小数的小数点向左移动一位，再扩大1000倍，得2012，则原来的小数是多少．
<gadget id="calculator">2_012 / 1_000</gadget>
<output>503/250 = around 2.012</output>

<gadget id="calculator">(503/250) * 10</gadget>
<output>503/25 = around 20.12</output>

<result>503/25 = around 20.12</result>
