Correct.  That's all our implementation does:  "RETURN (FLOAT(x));"

>>or is the
>>   PROCEDURE entier(x:REAL): INTEGER;
>>just another form of INTEGER(TRUNC(x)) ?

This one is a little different.  I understand it to be the "nearest integer
to REAL x".  So I guess it is a TRUNC with rounding.  Any REAL number with
a fractional part >= .5 is rounded up to the next highest integer.
Anything < .5 is equivalent to TRUNC(x).
