float argument - Terminator3 - 09.07.2011

how to return float as argument

Code:

void ReturnFloatArg(AMX* amx, cell param, double value)
{
	cell *cptr;
	amx_GetAddr(amx, param, &cptr);
	*cptr = amx_ftoc(value);
}

and use

Code:

ReturnFloatArg(amx, params[1], atof(str));

str is "100.0"
what is wrong?

sorry for my bad English

You should seriously have a look at the implementer's guide, otherwise you will never understand how it works. It explains you how to pass floats, strings and integers.

I'm going to quote some important paragraphs you probably need to learn, because your current structure is not going to work.

Quote:

The params argument points to an array that holds the parameter list of the function. The value of params[0] is the number of bytes passed to the function (divide by the size of a cell to get the number of parameters passed to the function); params[1] is the first argument, and so forth.

Quote:

The symbols amx_ctof and amx_ftoc are macros that cast a “cell” type into “float” and vice versa, but in contrast to the standard type casts of C/C++ they do not change the bit representation of the value that is cast.
