Can I ask what determines the precision of floating point calculations
are done in? It seems that fpc treats (for example, with J declared as
integer)
1/sqrt(J+1.0) as single
but
1/sqrt(J+1) as double
which seems counter-intuitive. In FORTRAN I can force double precision
evaluation with sqrt(J+1.0D0) but there is no equivalent idea of a
double constant in Pascal.
