Example
The following example illustrates how Trunc works with different arguments. Each line assigns a number to the vlResult variable. The comments describe the results:
vlResult:=Trunc(216.897;1) // vlResult gets 216.8
vlResult:=Trunc(216.897;-1) // vlResult gets 210
vlResult:=Trunc(-216.897;1) // vlResult gets –216.9
vlResult:=Trunc(-216.897;-1) // vlResult gets –220
