parseInt(11.4)

should be:

parseInt( '11.4', 10)

But I prefer Math.floor()

parseInt() acts nearly like Fix()
Math.floor() more like Int()

===========================

tested on IE6:

<script>
// javascript test, no type spec, sorry puritans

alert(parseInt( 11.4 ) ) // 11
alert(parseInt( -11.4 ) ) // -11
//alert(parseInt( 011.4 ) ) // error !!!!!
alert(parseInt( '011.4' ) ) // 9 octal !!!!
alert(parseInt( '-011.4', 10) ) // -11

alert(Math.floor( 11.4) ) // 11
//alert(Math.floor( 011.4) ) // error
alert(Math.floor( '011.4') ) // 11
alert(Math.floor( '-011.4') ) // -12

</script>

<script language=vbs>
// vbscript test, outdated type spec, sorry puritans
// alert is accepted as is the // instead of '

alert(Int( 11.4 ) ) ' 11
alert(Int( -11.4 ) ) ' -12
alert(Int( -011.4 ) ) ' -12

alert(Fix( 11.4 ) ) ' 11
alert(Fix( -11.4 ) ) ' -11

</script>

It said the radix was optional but prefix 0x would be seen as hex and prefix
0 octal, all others decimal.
It [docs] also said it wants a string but didn't complain when I passed a
float. Go figure.

Ya', the signed numbers make the difference.

function parseit(x) {
var a = parseInt(x);
WScript.Echo(a);
}
parseit(11.4);
parseit(-11.4);

Results: 11, -11

function floorit(x) {
var a = Math.floor(x);
WScript.Echo(a);
}
floorit(11.4);
floorit(-11.4);

Results: 11, -12

WScript.Echo(Int(11.4))
WScript.Echo(Int(-11.4))

Results: 11, -12
