title: Print constant exponent value using printf in c
body: <p>I used <code>%e</code> format specifier. Tried <code>%3.2e</code> or <code>%4.3e</code>.</p>
  
  <p>Example:<br>
  if <code>var=0.001342</code>, then I want to print <code>0.1342e-02</code>. But prints <code>1.342e-03</code><br>
  if <code>var=0.543124</code>, then I want to print <code>54.3124e-02</code>. But prints        <code>5.43124e-01</code><br>
  if <code>var=0.0123653</code>, then I want to print <code>1.23653e-02</code>.</p>
  
  <p>That is what ever maybe the value, I just want to fix my exponent value an print the result.</p>
