Syntax

SELECT [westclintech].[wct].[IMREAL] (
   <@inumber, nvarchar(4000),>)

Description

Use the scalar function IMREAL function to return the real coefficient of a complex number in the x + yi or x + yj format.

Arguments

@inumber

is the value at which to evaluate the function. @inumber is an expression of type varchar or of a type that can be implicitly converted to varchar and must be in the format x + yi or x + yj, where x is a real number that can be converted to float and yi (or yj) is an imaginary number, where the y part can be converted to float.

Return Type

float

Remarks

Use COMPLEX to convert real and imaginary coefficients into a complex number.

Examples

select wct.IMREAL('7+24i');

This produces the following result.

{"columns":[{"field":"column 1","headerClass":"ag-right-aligned-header","cellClass":"ag-right-aligned-cell"}],"rows":[{"column 1":"7"}]}

select wct.IMREAL('-i');

This produces the following result.

{"columns":[{"field":"column 1","headerClass":"ag-right-aligned-header","cellClass":"ag-right-aligned-cell"}],"rows":[{"column 1":"0"}]}

select wct.IMREAL('7');

This produces the following result.

{"columns":[{"field":"column 1","headerClass":"ag-right-aligned-header","cellClass":"ag-right-aligned-cell"}],"rows":[{"column 1":"7"}]}
