Token Size. It returns the greatest integer less than or equal to X , and also works on complex numbers, lists and matrices.
The difference between iPart and int is subtle, and many people aren't even aware of it, but it exists. Whereas iPart always truncates its parameters, simply removing the fractional part, int always rounds down. This means that they return the same answers for positive numbers, but int will return an answer 1 less than iPart for non-integer negative numbers.
For example, iPart Most of the time, however, you're dealing with only positive numbers anyway. In this case, the decision to use iPart or int is mostly a matter of preference - some people use int because it is shorter; some use iPart when there is a corresponding fPart taken. However, if speed is a consideration, one should check the Command Timings section.
The following table compares the speeds of int and iPart. Each command was timed over iterations to find a noticeable difference. Conclusion: int scales with the length of its input while iPart does not. For fewer than 6 decimals, int will most often be faster; for 6 or more decimals, consider using iPart.
