Conversions

    From Expressions

  • Suitably sized Complex expressions with real and imaginary parts that are Real can be converted into compiled elements with the type "ComplexReal64".

    • To Expressions

  • Compiled elements with the type "ComplexReal64" can be converted into Complex expressions with Real real and imaginary parts.

    • Arithmetic

  • Integers and reals are automatically promoted to "ComplexReal64" elements when they are combined in binary arithmetic operations.

Runtime Errors

    Overflow

  • "ComplexReal64" can give a runtime error if it is used in an operation that overflows.

Examples
