format string to number

[unkown]

Hi,
i'm writing a function in infopath which handle some calculation
my case as below:
155/3 = 51.6666666
i use the application.formatstring function to extract to nearest 2 decimal
places.
temp = Application.FormatString(155/3, "number", "numDigits:2")
the result of temp is "51.67"
but when i use temp to calculate somethings, it will hv error
coz the temp is string format, then how can i convert to number format after
extract to neatest 2 decimal places ?

If you're using JScript try using the parseFloat method (see

But if i want to get to nearest to 2 decimal places ?
e.g 4.6582612354 -> 4.66

Thanks

Look into using the "Number" object. It has a "toPrecision" method you can
use to set the amount of decimal places (see
http://msdn.microsoft.com/library/e...37-cf6c-46cc-bafa-04be1fe3d78d.asp?frame=true).

Do something like:
var myNum = new Number("4.6582612354");
var my2DecNum = myNum.toPrecision(3);

I haven't tested this, so if it doesn't work, get back to me.
