FIX _ _ _ _ _ _ _ _ _ _ _ _ operator
The operator fix returns the integer part of its argument, if that argument has a numerical value. For positive numbers, this is equivalent to floor, and, for negative numbers, ceiling. For non-numeric arguments, the value is an expression in the original operator.
fix 3.4; 3 floor 3.4; 3 ceiling 3.4; 4 fix(-5.2); -5 floor(-5.2); -6 ceiling(-5.2); -5 fix(a); FIX(A)
