Parameters

value
Double

the value to be represented by the Double.

Attributes

Remarks

Constructs a newly allocated Double object that represents the primitive double argument.

This member is deprecated. It is rarely appropriate to use this constructor. The static factory #valueOf(double) is generally a better choice, as it is likely to yield significantly better space and time performance.

Double(String)

Constructs a newly allocated Double object that represents the floating-point value of type double represented by the string.

[Android.Runtime.Register(".ctor", "(Ljava/lang/String;)V", "")]
public Double (string s);
[<Android.Runtime.Register(".ctor", "(Ljava/lang/String;)V", "")>]
new Java.Lang.Double : string -> Java.Lang.Double

Parameters

s
String

a string to be converted to a Double.

Attributes

Exceptions

if string cannot be parsed as a double value.

Remarks

Constructs a newly allocated Double object that represents the floating-point value of type double represented by the string. The string is converted to a double value as if by the valueOf method.

This member is deprecated. It is rarely appropriate to use this constructor. Use #parseDouble(String) to convert a string to a double primitive, or use #valueOf(String) to convert a string to a Double object.
