How can the parenthesis (. . . .) around a fraction be made larger?

[math ]\pm**\left(**\frac{1+i}{\sqrt2}**\right)**\;=\; \sqrt{i}[/math ]

This works forsize fraction:*any*

[math ] \left[ \frac{\dfrac{1}{4}+\dfrac{2}{3}}{5 + \dfrac{1}{2}} \right] [/math ]

\left and \right are certainly very useful. But they sometimes make parentheses that are larger than you really want. For example, there are situations where something like might be improved by writing it as , or even , using \biggl and \biggr (or \Bigl and \Bigr) instead of \left and \right.
