Number ( )

Initializes a new Number instance with a value of 0 (zero). This has the same affect as using a numeric literal with a value of zero.

Syntax:


Example:

i = new Number( ); // results in 0
// is equivalent to
i = 0;

Number ( Number )

Initializes a new Number instance to the specified number value.

Syntax:


Parameters:


Example:

i = new Number( 5.25 );
// is equivalant to
i = 5.25;

Number ( String )

Initializes a new Number instance by converting the specified string to a number.

Syntax:


Parameters:


Example:

s = "5.25";
i = new Number( s );

Number ( Boolean )

Initializes a new Number instance by converting a boolean to a number. false results in 0 (zero), and true results in 1.

Syntax:


Parameters:


Example:

b = true;
i = new Number( b ); // results in 1
