The explicit keyword above the symbolic evaluation operator is of limited use;
- its asthetically cumbersome (and confusing to human readers not familiar with mathcad) when keywords and their modifiers start stacking up. It also takes up significant space on the page (compounded by the inability to insert a carriage return).
- it doesn't allow decimal/digit display control over variables previously evaluated numerically, displaying instead long (20 digit) floating numbers
- the display of the variables is determined instead by whether they have been re-defined with limited float using the symbolic operator in previous lines (incidentally, this is strangely dependent on whether the re-defination happens on the same line as the original variable definition, or later on its own line) - this affects the accuracy of the calculation as the number's actual value is truncated.
- there is no way to wrap the right hand side of the equation onto a new line when it (frequently) runs off of the side of the page (line break operators only work on the left hand side of the equation.)
A MORE ELEGANT SOLUTION:
Get rid of the keyword explicit and all of its modifiers (or keywords generally). Instead, allow the user to right-click the right hand side of an equation and choose from a pop-up menu to show the equation in its "explicit" or evaluated state, leaving the operator display a simple arrow (or better yet; equality symbol). Allow the user to right-click any term in the right hand of an equation and choose whether to show it as a variable or a numeric value with digit/decimal display control (affecting display only, the actual number should maintain its float in the background). Allow the user to insert carraige returns where they see fit.
