Hi
The command 'bool(3<pi)' takes 0.1 second on my machine. This
makes plotting/computing piecewise-defined trigonometric functions
rather slow.
The culprit seems to be sage.calculus.SymbolicExpression.__lt__(self, right).
It always yields a SymbolicEquation, which is then solved in Maxima.
Maybe we can speed this up with a check along the line of,
if ( self is constant
and type(right) is Integer, RealNumber,... ):
temp = self, coerced into RealNumber with appropriate precision.
return temp.__lt__(right)
Related issue: '3<4' yields a bool, while '3<pi' yields an
instance of SymbolicEquation. Maybe '3<pi' should just yield a
bool too.
