Summary

Returns an integral number, whose value depends upon the nature of the parameter's numeric value:

  • If that numeric value is an exact integer, the number returned has exactly the same value.
  • If that numeric value is not an exact integer, the number returned is the integer which is closest in value to the parameter's numeric value. Positive numbers which are exactly midway between adjacent integers are rounded upwards, while negative numbers which are exactly midway between adjacent integers are rounded downwards.
