ComplexConstant¶
A complex literal.
声明¶
语法¶
ComplexConstant(float re, float im, ttype type)
参数¶
Argument |
描述 |
|---|---|
|
the real part. |
|
the imaginary part. |
|
the complex type, which fixes the kind. |
返回值¶
The value of the expression.
描述¶
Both parts are stored as numbers. A complex literal whose parts are not both constants is a ComplexConstructor instead.
示例¶
