Variants

NotConvertable

An input cannot be converted to CalculatorFloat

FloatSymbolicNotConvertable

Fields

val: String

Value that can not be converted

A symbolic input cannot be converted to CalculatorFloat

ComplexSymbolicNotConvertable

Fields

val: CalculatorComplex

Value that cannot be converted

A symbolic input cannot be converted to CalculatorComplex

ComplexCanNotBeConvertedToFloat

Fields

val: CalculatorComplex

Value of the CalculatorComplex that cannot be converted
