DeePsea’s Calculator
Press A to access the popup calculator from the main edit screen or from most number boxes where you may desire to do calculations.
DeePsea’s calculator is simple and straight forward. Numbers and operators are entered one after the other. Precedence of processing is first come, first serve. The default operator is +. The last operator is repeated if no operator is given. For example, 3 6, means add 3 to 6, since + is the default. 3 * 6 means multiply 3 by 6 since * (multiply) is the last one.
Enter the numbers and operators one after the other. The operators are:
+ = add
 = subtract
* = multiply
/ = divide
