17 Numbers: Integer and Float

MDN: Numbers and Dates: Numbers

An Integer is a number without a decimal—a whole number—and a Float is a number with a decimal. All MIDI-specific values are handled as Integer and most Scripter-specific values are handled as Float.

var anInteger = 60; 
var aFloat = 60.1;

When calculations are made between integers and floats, the result will always be a float.

var anInteger = 60; 
var aFloat = 60.1;
var result = anInteger + aFloat; // 120.1, a float
