Abstract

One example includes a method for assigning numerical indicators that each define a respective numerical format in a mathematical calculation. The method includes receiving a mathematical expression as an input. The mathematical expression includes at least one expression term. The method also includes assigning a first numerical indicator to each of the expression term(s) and performing at least one mathematical calculation provided by the mathematical expression to obtain a mathematical solution comprising at least one solution term. The method also includes assigning a second numerical indicator to each of the solution term(s) based on the first numerical indicator of each of the at least one expression term and based on rules defined in an indicator priority rule-set. The method further includes displaying each of the at least one solution term of the mathematical solution in a format corresponding to the respectively assigned second numerical indicator on a graphical display.

Dependent claims

A non-transitory computer readable medium that is configured, when executed, to implement a method for assigning numerical indicators that each define a respective numerical format in a mathematical calculation, the method comprising:

receiving a mathematical expression as an input, the mathematical expression comprising at least one expression term;
assigning, respectively, a first numerical indicator to each of the at least one expression term;
and
performing at least one mathematical calculation provided by the mathematical expression to obtain a mathematical solution comprising at least one solution term;
assigning, respectively, a second numerical indicator to each of the at least one solution term based on the first numerical indicator of each of the at least one expression term and based on rules defined in an indicator priority rule-set, wherein the rules are configured to match a format of the at least one expression term with a format of the at least one solution term;
and
displaying each of the at least one solution term of the mathematical solution in a format corresponding to the respectively assigned second numerical indicator on a graphical display;
wherein assigning the first and second numerical indicators includes:
storing the first numerical indicator associated with each of the at least one expression term as a data tag linked with each of the at least one expression term in a memory;
and
storing the second numerical indicator associated with each of the at least one solution term as a data tag linked with each of the at least one solution term in the memory.
