The parseFloat() Function

The parseFloat() function returns a floating-point value defined by the string value. 

The parsing ends on the first character that can not be parsed as a floating-point value.

Syntax

Example

var a = Lang.parseFloat("2345.14");
var b = Lang.parseFloat(" -4.45e2 Kg");
var c = Lang.parseFloat(" +4.45e2 Kg");
var d = Lang.parseFloat("-.3 C");
var e = Lang.parseFloat(" 300 ");

Result

a = 2345.14
b = -4.45e2
c = 4.45e2
d = -0.3
e = 300.0
