View Full Version : Converting "text" number to an actual number
01-11-2004, 01:56 AM
In recent postings I was shown how to pass numbers from one web page to another. That works great. The problem I have now is the numbers that were passed are text instead of numbers. Listed below are the numbers that were passed:
num1 = 100
num2 = 200
num3 = 300
If I were to add these numbers together on Page2.htm, the result would look like 100200300 instead of 600. Any ideas as I would convert these to actual numbers?
The posting where I obtain the coding:

parseInt( string, 10 ); // Integers with a radix of 10. (IOW, decimal integers)
parseFloat( string ); // Floating point numbers, radix of 10. (IOW, decimal floating point numbers)

Thanks guys for your help. I'm still having problems, however, converting the textstring numbers to numeric numbers. To test the conversion, I created two numbers, one as a text string and the other as a numeric number. I used the number function, but it didn't convert it. It should have returned the answer:
Instead, it returned:
Any ideas? I also used the parseInt and got the same results. Listed below are the codes I used.

Ah, the input is not changed when you use those functions - the output from them is changed, however. An example:
sNumber = '100.1', // => [string '100.1']
iNumber = parseInt( sNumber ), // => [number 100]
nNumber = parseFloat( sNumber ); // =>[number 100.1]
/* The results?
sNumber is still a string '100.1'
iNumber is a number 100
and nNumber is a number 100.1
