This is normal behaviour. The div operator is used to divide 2
numbers. Applescript converts both numbers to integers (if they're
not already integers), performs the division, and discards any
fractional remainder. The result is always an integer. Use / instead
of div.
Oh, you're perfectly correct !
Am I misreading, or are these answers missing the point?
102.0 div 1 ought to yield 102, not 101.
set n to 1.015 * 100 --> 101.5
set n to n + 0.5 --> 102.0
n div 1 --> 101 --> (!)
The workaround for the "affected routines" would be coercing n to
"small
real" (if you wish to preserve decimals) before using div.
Julifos did not mean to say he wanted to preserve decimals in the
final
result. But rather that
set n to 1.015 * 100 --> 101.5
set n to n + 0.5 --> 102.0
(n as small real) div 1 --> 102
gets the right answer. (102)
So does:
set n to 1.015 * 100 --> 101.5
set n to n + 0.5 --> 102.0
n as integer --> 102
Since that's what he's apparently looking for, better to use this
coercion.
