Two built-in functions are available in HP Pascal/HP-UX.
roundlong |
 |
The roundlong
function returns the longint
value of the argument, rounded to the nearest integer. If x
is positive or zero, roundlong(x)
is equivalent to trunclong(x+0.50);
otherwise, roundlong(x)
is equivalent to trunclong(x-0.50).
It is an error if the result is greater than 263-1
or less than -263.
where x is any real
or longreal expression.
trunclong |
|
The trunclong
function returns the longint
value of the argument, with any fraction truncated. The absolute
value of the result is not greater than the absolute value of x.
It is an error if the result is greater than 263-1
or less than -263.
where x any real
or longreal expression.
