Methods Detailed

toExponential()

Returns a string representing the number in exponential notation.

Returns: String A string representing the number in exponential notation.

Sample

var n = 123.45678;
application.output(n.toExponential(3));

toExponential(fractionDigits)

Returns a string representing the number in exponential notation.

Parameters

• Number fractionDigits An integer specifying the number of digits after the decimal point. Defaults to as many digits as necessary to specify the number.

Returns: String A string representing the number in exponential notation.

Sample

var n = 123.45678;
application.output(n.toExponential(3));

toFixed()

Returns a string representing the number in fixed-point notation.

Returns: String A string representing the number in fixed-point notation.

Sample

var n = 123.45678;
application.output(n.toFixed(3));

toFixed(digits)

Returns a string representing the number in fixed-point notation.

Parameters

• Number digits The number of digits to appear after the decimal point. Defaults to 0.

Returns: String A string representing the number in fixed-point notation.

Sample

var n = 123.45678;
application.output(n.toFixed(3));

toLocaleString()

Converts the number into a string which is suitable for presentation in the given locale.

Returns: String A string representing the number in the current locale.

Sample

var n = 1000000;
application.output(n.toLocaleString());

toPrecision()

Returns a string representing the number to a specified precision in fixed-point or exponential notation.

Returns: String A string representing the number to a specified precision in fixed-point or exponential notation.

Sample

var n = 123.45678;
application.output(n.toPrecision(5));

toPrecision(precision)

Returns a string representing the number to a specified precision in fixed-point or exponential notation.

Parameters

• Number precision An integer specifying the number of significant digits.

Returns: String A string representing the number to a specified precision in fixed-point or exponential notation.

Sample

var n = 123.45678;
application.output(n.toPrecision(5));

toString()

Returns a string representing the specified Number object.

Returns: String A string representing the specified Number object.

Sample

var n = 7;
application.output(n.toString()); //displays "7"
application.output(n.toString(2)); //displays "111"

toString(radix)

Returns a string representing the specified Number object.

Parameters

• Number radix An integer between 2 and 36 specifying the base to use for representing numeric values

Returns: String A string representing the specified Number object.

Sample

var n = 7;
application.output(n.toString()); //displays "7"
application.output(n.toString(2)); //displays "111"
