  DESCRIPTION:
    The lrint function rounds its argument to the nearest integer value of
    type long int, rounding according to the current rounding direction. 
  RETURN VALUE: 
    If the rounded value is outside the range of the return type or the 
    argument is infinity or NaN, the result is the largest negative value
    and the invalid exception is signaled
  EXCEPTIONS SIGNALED: 
    invalid and inexact
