To generate the Go code for the new 39 math functions that were introduced in GeneXproTools with Mini-Release 1, I decided to use the VB.Net code instead of the C++ code like Glenn did for the Go Math Grammar (see the previous post "Support for the Go Language in GeneXproTools"). And the main reason for this choice is that I can use "Then", "End If", "Else" and "ElseIf" to put the curly braces of the Go language neatly in place.
There are also other reasons for choosing the VB.Net Grammar as template instead of the C++ Grammar and that includes the fact that both Go and VB.Net have built-in min and max functions, which, in this particular case of the new 39 math functions, means less modifications to the code as we are evaluating min and max values in quite a few places in the code.
So, in all, the required modifications to the VB.Net code include replacing "Then" by "{", "End If" by "}", "Else" by "} else {", "ElseIf" by "} else if", "If" by "if", "Return" by "return", "End Function" by "}", "<>" by "!=", "And" by "&&", "Min" by "math.Min", "Max" by "math.Max", "Constant SLACK As Double" by "const SLACK", "As Double =" and "As Integer =" by ":=" and then remove "Dim" and change the comment marks to "//".
And finally, we also need to take care of the function declarations, which are different in both programming languages. But again, these are easily done by replacing each of the four templates (one for each of the four types of functions: functions of 1, 2, 3, and 4 arguments) by the correct one.
So here's the Go code for the new 39 math functions that were added to the built-in math functions of GeneXproTools 5.0 with Mini-Release 1 (note however that the Go Programming Language will only be available in GeneXproTools with the next mini-release):
