There is an inconsistency in the behaviour of the cosine function sage: type(cos(1)) <type 'sage.symbolic.expression.Expression'> sage: type(cos(pi)) <type 'sage.symbolic.expression.Expression'> sage: type(cos(0)) <type 'int'>
It also happens with the sine: sage: type(sin(0)) <type 'int'> sage: type(sin(pi)) <type 'sage.symbolic.expression.Expression'> and the exponential: sage: type(exp(0)) <type 'int'> sage: type(exp(1)) <type 'sage.symbolic.expression.Expression'> the logarithm: sage: type(log(1)) <type 'int'> sage: type(log(2)) <type 'sage.symbolic.expression.Expression'> sage: type(log(0)) <type 'sage.symbolic.expression.Expression'> Is there some reason for this or is it a bug? Shouldn't the answer be, at least, a sage Integer and not a python int? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
