Hi,

Trying to use IDE Calculator function.

When I use IDE Calculator in IDE. (Ctrl+e) I get following result.

$A=100
100 0x64 "d"
$B=32.5
32.5
$A+B*(32-56/2)
230 0xe6 "æ"
$C=A+B*sin(3.0)
104.5864

But when I use same code from uppsrc/ide/Calc.cpp in my program I get following result.
It gives ERROR: void.sin(): (0,15): 'sin' is not a lambda for sin() function.

A=100 -- Result -- 100
B=32.5 -- Result -- 32.5
A+B*(32-56/2) -- Result -- 230
C=A+B*sin(3.0) -- Result -- ERROR:  void.sin(): (0,15): 'sin' is not a lambda

Code used, ESC Package to be added to Package
What changes in code required to process trigonometric functions correctly. Is working code
This is code taken from uppsrc/ide/Calc.cpp

#include <Core/Core.h>
#include <Esc/Esc.h>

using namespace Upp;

ArrayMap<String, EscValue> vars;

ArrayMap<String, EscValue>& UscGlobal()
{
	static ArrayMap<String, EscValue> global;
	return global;
}

void Calc(String exp)
{
	String txt;
	try {
		ArrayMap<String, EscValue>& g = UscGlobal();
		for(int i = 0; i < g.GetCount(); i++)
			vars.GetAdd(g.GetKey(i)) = g[i];
		if(IsNull(exp))
			return;
		EscValue v = Evaluatex(exp, vars);
		txt = v.ToString();
		vars.GetAdd("_") = v;
	}
	catch(CParser::Error e) {
		const char *x = strchr(e, ':');
		txt << "ERROR: " << (x ? x + 1 : ~e);
	}
	LOG(exp << " -- Result -- " << txt);
	
}

CONSOLE_APP_MAIN
{
        StdLib(UscGlobal());
	String s = "A=100";
	Calc(s);
	s = "B=32.5";
	Calc(s);
	s = "A+B*(32-56/2)";
	Calc(s);
	s = "C=A+B*sin(3.0)",
	Calc( s );
}

WIN10 - visual studio 14.0 - 64 bit.
IDE is compiled from source. Ver 10553

Warm Regards
