Letter 'C' in argument doesn't work

[nikiGagliardi]

Hi guys,

I have some problem with the letter 'C', when I set this letter, mxparser fails to process the function is the letter C used for other purposes in mxparser ?

not work

char letter = 'C';
var formula = $"{letter}*100";
Expression e = new Expression(formula);

var argument = $"{letter} = 10";
e.addArguments(new Argument(argument));


Console.WriteLine(e.checkSyntax());
Console.WriteLine(e.getExpressionString());
Console.WriteLine(e.calculate());

work

char letter = 'A';
var formula = $"{letter}*100";
Expression e = new Expression(formula);

var argument = $"{letter} = 10";
e.addArguments(new Argument(argument));


Console.WriteLine(e.checkSyntax());
Console.WriteLine(e.getExpressionString());
Console.WriteLine(e.calculate());
