HP Pascal/iX Enhancements

Two new built-in functions, roundlong and trunclong, are available in
this version of HP Pascal/iX.

roundlong 

Syntax 

     roundlong (x)

where x is any real or longreal expression.

The roundlong function returns an argument rounded to the nearest
longint.  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.

trunclong 

Syntax 

     trunclong (x)

where x is any real or longreal expression.

The trunclong function returns the longint part of a real or longreal 
expression; that is, the integral part of its argument.  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.

These features are part of standard HP Pascal.
