Very Quick, Easy Question

[Prismatic]

Hello,I was wondering if there was a JavaScript function that allowed the transfer of a variable's value from that of a string to a math object. I know how to use the to string method to do the opposite of this, but is the vice-versa also possible? I have searched for quite a while to find such a funtion, and I'm wondering now if it even exists.For example, if I have a variables value set to " a = '1' ," is there any way I can change the value of "a" to read, " a = 1 "?Thanks for reading.

Hi vijay, Prismatic,I think what Prismatic is looking for is javascript's "Number()" or "parseInt()".

The Number() function converts the value of an object to a number.

The parseInt() function parses a string and returns an integer.

A link reference for Number():http://www.w3schools.com/jsref/jsref_Number.aspparseInt():http://www.w3schools.com/jsref/jsref_parseInt.aspparseFloat():http://www.w3schools.com/jsref/jsref_parseFloat.aspTo my knowledge there is no function that converts the variable, you have to reassign it:

<script type="text/javascript">var a = "125.35";alert(a + 3); //a treated as Stringalert(Number(a) + 3);alert(a + 3); //a is still a Stringa = Number(a);alert(a + 3);</script>

Thanks,

Also, if you're using math functions with variables, you can do this:

x="1"y="1"z=eval("x+y")alert(z)

That would alert the number 2. The eval function does that.
