(parse-double s)(read-string s)Uses the Clojure reader to parse a string into a float and is thus platform agnostic.
(Float/parseFloat s)This calls down to Java, and thus only when running Clojure on that platform.
float f = std::stof(s);var f=float.Parse(s);f = num.parse(s);f = String.to_float(s)read(s,'(g0)')fread (unit=s,fmt=*) fread s :: DoubleYou can convert to Double or to Float.
let f = +sThe unary + operator converts its argument to a double precision floating point.
double f = Double.parseDouble(s);
Will throw NullPointerException if s is null or NumberFormatException if s does not actually represent a float.
Float f = Float.valueOf(s);Double f = Double.valueOf(s);f := s.ToExtended;* Works correctly in Lazarus IDE v. >= 1.8.0.
* Type Float = Extended
* Type Float = Extended
my $f = $s;s = u'545,2222'
locale.setlocale(locale.LC_ALL, 'de')
f = locale.atof(s)When working with different locale decimal and thousand separators you have to use locale.atof
f = float(s)f = float(s)f = s.to_fThis method never raises an exception.
