Remarks
The string representation of the complex number returned by this method displays the number using its Cartesian coordinates in the form <a; b>
(or (a, b)
in .NET 7 and earlier versions), where a is the real part of the complex number, and b is its imaginary part. Both a and b are formatted using the format string specified by format
. The format
parameter can be any valid standard numeric format specifier, or any combination of custom numeric format specifiers. If format
is equal to String.Empty or is null
, the real and imaginary parts of the complex number are formatted with the general format specifier ("G"). If format
is any other value, the method throws a FormatException.
.NET provides extensive formatting support, which is described in greater detail in the following articles:
- For more information about numeric format strings, see Standard Numeric Format Strings and Custom Numeric Format Strings.
- For more information about formatting in .NET, see Formatting Types.
The provider
parameter is an IFormatProvider implementation. Its GetFormat method returns a NumberFormatInfo object that provides culture-specific information about the format of the real and imaginary numbers in the returned string. Depending on the format
parameter, this object controls symbols such as the negative sign, the group separator, and the decimal point symbol in the output string. If provider
is null
, the returned string is formatted using the NumberFormatInfo object of the current culture.
The provider
parameter can be one of the following:
- A CultureInfo object that represents the culture that supplies formatting information
- The NumberFormatInfo object that supplies formatting information.
- A custom object that implements the IFormatProvider interface. Its GetFormat method returns the NumberFormatInfo object that supplies formatting information.
