Subject: bug#10554: 24.0.92; No units specified (dimensionless quantities in Emacs Calc)
Date: Wed, 18 Jan 2012 23:24:41 -0600 [thread overview]
Message-ID: <8762g8i7s6.fsf@niu.edu> (raw)
In Calc type
'e T m^2 / hbar
Convert this to SI units with u c si RET
- That's perfect. We get a dimensionless number.
Let's try again. In Calc type (more my range of numbers)
'e T nm^2 / hbar
Now when we type again u c, Calc remembers what we did before.
So as a unit it offers "default 1". Let's take this default.
So just type RET
Error: No units specified
In other words: if an expression with units simplifies to a
dimensionless number, Calc does not accept the unit "1", though it
even offers this unit as a default for calc-convert-units.
