cadence calculator?

If I enter 5/3 in the Cadence calulator, I get 1 instead of 1.666667.
How do I specify how many digits to display?

aelPushSignifDigits(10) doesn't work

 

When specifying integers as operands, Cadence just performs integer
calculation. You have to enter 5.0/3 to get the desired result.

Erik,

5/3 is an integer division, and so the correct answer is 1. It's not to do with
precision. You need to do either:

5.0/3
5/3.0
5.0/3.0

(having one of the numbers as a float will force the calculation to
be done as a float). Whilst this might seem unusual in a calculator, it is
not unusual in a programming language (the same behaviour would be seen
in C). Since the calculator is in essence a SKILL expression builder, and
SKILL has the same kind of rules as C for algebraic expression handling,
that's why this happens.

aelPushSignifDigits only has an affect on ael expressions (such as instance
parameter expressions), not SKILL. SKILL evaluates to the full double
precision floating point - provided that the expression is a floating
point expression rather than an integer expression. However, it would
normally just show up (in the default print representation) using around
6 or 7 digits - to get SKILL to display return values with greater precision
you can use:

sstatus(fullPrecision t)

I understand what you guys are saying, but I don't like it. I would
expect that the Cadence calculator would act the same as my pocket
calculator. If I want to do integer division, then I could just use
the floor() function.

Erik,

You might not like it, but it has been this way for many, many years, and to
change it would bring about an incompatibility which would break things for
people who are depending on this behaviour.

Other languages also have the concept of integer arithmethic too - (C for
example) - if there is nothing to cast the type, then it should use the type of
the numbers. We certainly can't change it in SKILL without breaking things.

Andrew.
