• toFixed(fractionDigits)
• toExponential(fractionDigits)
• toPrecision(precision)

The toFixed(fractionDigits) method formats a number with fractionDigits digits after the decimal place. Suppose:

x = 1234.56789

The toExponential(fractionDigits) method formats a number with fractionDigits digits after the decimal place, in exponential notation. Suppose:

x = 1234.56789

The toPrecision(precision) method formats a number with total precision number of digits, in exponential notation if needed. Suppose:

x = 1234.56789

When you call alert(x.toPrecision(9)), you'll get 1234.56789 in IE5.5.

Exprience some of these functions by yourself in Column 59, IE 5.5: Formatting, URIs, and Stack Operations.
