fix(+Number, -Result)

Unifies the integer part of Number with Result (Truncation towards zero).
A number.
Output: integer.


This predicate is used by the ECLiPSe compiler to expand evaluable arithmetic expressions. So the call to fix(Number, Result) is equivalent to
    Result is fix(Number)
which should be preferred for portability.

This function is deprecated. For clearer code, please use

    Result is integer(truncate(Number)).

In coroutining mode, if Number is uninstantiated, the call to fix/2 is delayed until this variable is instantiated.

Modes and Determinism


(4) instantiation fault
Number is not instantiated (non-coroutining mode only).
(5) type error
Number is of type breal.
(24) number expected
Number is not of a numeric type.


    Result is fix(1.5).		% gives Result = 1
    Result is fix(-6.4).	% gives Result = -6
