btw, I've never programmed in a Pascal-like language, despite having a
go at Modula-2 ages ago...
in a program which uses C family syntax ? C++, C#, Java none of which have
the Real type.
Maybe it's because I cut my teeth on Fortran? And I haven't programmed
in anger in C for a while.
Anyways, I did say "something like" - I'm remembering back to some time
in the mid-90s.

In reality, you could well be correct !!!
When I was involved in recruiting a C programmer ages ago, we set a simple
competence test. I lifted a snippet of code from one of OUR OWN programs
somewhere that said something like ...
real rr = our value of interest;
int ii = rr*10;
int mm = ( rr - (float(ii)/10) ) * 10;
if (mm>5)
float rr2 = int( rr + .5 );
else
float rr2 = int( rr);
We asked the candidates to identify what this code was doing, and could they do
it any simpler. We made a point of saying that all we wanted was for them to
spot what was going on ...
With only ONE exception, every candidate rewrote it and made it even more
convoluted. That one exception got it right ...
rr2 = round( rr);
Cheers,
Wol
