Try to find a value for the expression from any equations defined previously in the document. A value is expected to be a quantity, that is a number with optional units. If the expression cannot be reduced to a quantity, it will be reduced to numerical values as far as possible.

	The expression will contain rational numbers, not floats, unless a conversion to a floating point number is required to obtain a quantity. This might be the case e.g. if the expression contains square roots of rational numbers. If you want to force a conversion to floats, use <code>[[QUANTITY]]</code> instead.		The expression will contain rational numbers, not floats, unless a conversion to a floating point number is required to obtain a quantity. This might be the case e.g. if the expression contains square roots of rational numbers. If you want to force a conversion to floats in this case, use <code>[[QUANTITY]]</code> instead.

			If the expression cannot be evaluated to a quantity (e.g. some symbolic elements remain), then iMath will retain mathematical precision. For example, square roots will not be evaluated to floating point numbers. If you want this, use [[SIMPLIFY]] with the <code>eval</code> simplification.
