WmPublic. Subtracts one integer (represented as a String) from another and returns the difference.

Make sure the result of your calculation is less than 64 bits in width (the maximum width for the long data type). If the result exceeds this limit, it will generate a data overflow.

Make sure the strings that are passed to the service in num1 andnum2 are in a locale-neutral format (that is, using the pattern -####.##). Passing locally formatted strings may result in unexpected results. For example, calling pub.math:addFloats in a German locale with the arguments 1,23 and 2,34 will result in the value 357, not 3.57 or 3,57.
