title: Min positive value for float?
body: <p>I'm new to C++!</p>
  
  <p><a href="https://en.wikipedia.org/wiki/Single-precision_floating-point_format" rel="noreferrer">Wiki says</a> this about <code>float</code>: The minimum positive normal value is 2^−126 ≈ 1.18 × 10^−38 and the minimum positive (denormal) value is 2^−149 ≈ 1.4 × 10^−45.</p>
  
  <p>But if a float can have max 7 digit (<code>≈ 7.225</code>), the min is it not just <code>0,0000001</code>? I'm confused :)</p>
