Truncate floating-point value of argument to integer.
val = trunc(someval)
trunc returns the truncated (integer part) value of someval. Like all Minc functions, however, it returns it as a double (floating-point) value. For example
val = trunc(14.154978)
will set val to 14.0. This differs from the round scorefile command in that round will return the closest int, where trunc simply ignores the values after the decimal point.
truncval = trunc(arbitrary_val)
