	<code>realroots = true \| false</code> Specifies whether iMath should return real nth roots as the result of [[VAL]] where the base is negative. By default, the root on the principal branch is returned (which is complex for negative bases). For example, the third root of <code>-1</code> would be returned as <code>1/2 + 1/2 * sqrt(3) * I</code>.		<code>realroots = true \| false</code> Specifies whether iMath should return real nth roots as the result of [[VAL]] where the base is negative. By default, the root on the principal branch is returned (which is complex for negative bases). For example, the third root of <code>-1</code> would be returned as <code>1/2 + 1/2 * sqrt(3) * I</code>.

			==== Allow implicit multiplication ====
			<code>implicitmul = true \| false</code> Specifies whether iMath should be able to infer a multiplication symbols between two adjacent variabels, e.g. <code>y = a x^2 + b x + c</code>. Turning off implicit multiplication forces the notation for this example to be e.g. <code>y = a cdot x^2 + b cdot x + c</code>.

			Please note that not all combinations of the following options make sense. Here are two examples
			* <code>precision=0;fixedpoint=false</code> It is not possible to display any number with zero significant digits
			* <code>x=12.3456</code> with <code>precision=0;fixedpoint=true;exponent=2</code> Fixed point and zero precision forces iMath to display no digits after the decimal marker. But the exponent of 2 results in a number smaller than 1 being printed. The result will be <code>0. cdot 10^2</code>.
