Format a decimal number to an Integer

[Tusk]

I want to use a result for furtherer calculations but only want the whole number and not the decimal portion. In Excel there is a function "=INT(A1)" this ignores the decimal values in cell "A1", e.g. if call "A1=5.345"and I use the following function in cell "A2" "=INT(A1)*3" I get the result "15"How do I do this in JavaScript ?Thanks

you can use javascript's native Math object and use the floor method.http://www.w3schools.com/jsref/jsref_obj_math.asp

Math.round() will round the number to the nearest integer, either up or down. floor() rounds down, and ceil() rounds up.

or use parseInt which produces the same result as excel int() as math.floor() and as math.ceil() would for floor() and ceiling() in excel.var a = 5.345;var b = parseInt(a)*3;
