IsUndefinedExactly(AngouriMath.Entity)
Method (no overloads)
Summary
Whether substituted , with no symbol left in it, has no value because
some function in it is undefined at its arguments: a node whose arguments are all exact
numbers and whose own value is not a finite number.x^i + x at 0 is one, since
0^i is undefined, so 0 is not a root of x^i + x = 0 however small the
compiled function Newton's method iterated on is there.

numbers and whose own value is not a finite number.

Remarks
A residual that is not finite is otherwise no evidence against a root: a root found in
decimals carries rounding, and a function taken at it next to the edge of its domain, or
a term that overflows, may have no value where the root itself gives one. Exact arguments
have neither to come from. https://github.com/asc-community/AngouriMath/issues/2424
