title: d programming, parse or convert string to double
body: <p>as easy as it is in other languages, i can't seem to find an option in the d programming language where i can convert a string (ex: "234.32") into a double/float/real. </p>
  
  <p>using atof from the std.c.stdio library only works when i use a constant string. (ex: <code>atof("234.32")</code> works but <code>atof(tokens[i]);</code> where tokens is an dynamic array with strings doesn't work).</p>
  
  <p><em>how to convert or parse a string into a real/double/float in the d-programming language?</em></p>
