Is there a preferred way of taking numerical approximation of a quantity in Sage with units of measure? Here is a contrived example:
r = 123/47 * units.length.meter r area = pi * r^2 area output: 123/47*meter 15129/2209*pi*meter^2 Now imagine that r is not a literal but the result of other calculations involving units of measure, so you can't easily apply n() at the time of assignment to r. Is there a simple way to take n() of things without getting into the following? # "n(r)" n(r.coeffs()[0][0]^r.coeffs()[0][1])*r.args()[0] ==> 2.61702127659574*meter # "n(area)" (n(area.coeffs()[0][0])*(area.args()[0])^area.coeffs()[0][1]) ==> 21.5161409036487*meter^2 ### -- You received this message because you are subscribed to the Google Groups "sage-support" group.
