Typecast Float to String

If an float produces an number like for example 7.850000, is there an good way to typecast it to an string and keep all the numbers after the coma? For example 7.85 or in worst case 7.850000?

It's not a very big deal if I keep all the zeroes, i'll just delete them with llDeleteSubString (I think it is), but I'd need to keep the .85 part of the float.

did you try to typecast it?

float x=7.85;
string s=(string)x;

that should do it

http://wiki.secondlife.com/wiki/Float2String might be what you need.

if you are just looking to chop trailing zeros off, it's actually the more difficult problem, which can be tackled 2 ways....

method one: loop through the back end until you hit something besides zero, then remove everything after it.

string uTrimFlt2Str( float vFltSrc ){
	if (vFltSrc == (integer)vFltSrc){
		return (string)((integer)vFltSrc);
	}
	else{
		string vStrSrc = (string)vFltSrc;
		integer vIntCnt = llStringLength( vStrSrc );
		while ("0" == llGetSubString( vStrSrc, --vIntCnt, vIntCnt  )){
		}
		return llGetSubString( vStrSrc, 0, vIntCnt );
	}
}

method two, convert zeros to spaces, and trim them off the end.

string uTrimFlt2Str( float vFltSrc ){
	if (vFltSrc == (integer)vFltSrc){
		return (string)((integer)vFltSrc);
	}
	else{
		return llDumpList2String(
		       llParseString2List(
		       llStringTrim(
		       llDumpList2String(
		       llParseStringKeepNulls(
		       (string)vFltSrc, ["0"], [] ),
		       " " ),
		       STRING_TRIM_TAIL ),
		       ["  "], [] ),
		       "0" );
	}
}

trailing decimals are removed by integer comparison in the first test (if they exist) otherwise all zeros are truncated
