adding values with decimal or float..

tinchie8

Hi,

when i tried this one:

var $value = 1.2;
for (var $ctr=0; $ctr <= 4; $ctr++){
_setValue(_textbox("txt_value"), $value);
$value = $value + 0.1;
}

i got these results for $value:

1.2
1.3
1.4000000000000001
1.5000000000000002


.... how do i make 1.4000000000000001 and 1.5000000000000002 to be just 1.4 and 1.5??

in C we got this %.2f, but in SAHI i dont know how to do this.....

Anyone know how??

would greatly appreciate your help...

Thanks

Hi,

If its always like you have one digit to left of the decimal place then use
$value = Math.round($value*100)/100;

Another option is to use toFixed() if you just want to chop off the extra digits.
