Converting String to Numbers


If you have a string and want to convert it to a number then use the parseInt() method. For example this script returns integer values containing 1234 and 43 respectively into X:

X = parseInt("1234",10);

X = parseInt("34abc",10);

  

The second argument (10) specifies you want to use a base 10 numbering system. It's unusual to use anything for this parameter except 10 and you should always specify it as the default is a bit unpredictable. (See, for example, http://www.w3schools.com/jsref/jsref_obj_global.asp if you are interested as to why)

If you need to have decimals then use parseFloat(). For example this script returns floating point values 1234.345 and 34.7 respectively into X:    

X = parseFloat("1234.345");

X = parseFloat("34.7abc");

  

Remember that these are floating point values so they are not always as accurate or as predictable as signed or packed decimals numbers.
