A number or a result of a numeric operation was outside of the range allowed by Number.

Number is a doube precision floating point number as specified by the IEEE 754 standard. Therefore the range of representable numbers is huge (-1.7*10308 to 1.7*10308), but still finite (special number such as infinity and NaN are not allowed by GeoGen).
