Float2String

De DigiWiki.

Example:

string myFormattedFloat = Float2String(-7.1373699, 3, TRUE);<br /> //rounded
//returns "-7.14"
 
string myFormattedFloat = Float2String(-7.1373699, 3, FALSE);<br /> //not rounded
//returns "-7.13"

Specification:

string Float2String ( float num, integer places, integer rnd) { 
//allows string output of a float in a tidy text format
//rnd (rounding) should be set to TRUE for rounding, FALSE for no rounding
 
    if (rnd) {
        float f = llPow( 10.0, places );
        integer i = llRound(llFabs(num) * f);
        string s = "00000" + (string)i; // number of 0s is (value of max places - 1 )
        if(num < 0.0)
            return "-" + (string)( (integer)(i / f) ) + "." + llGetSubString( s, -places, -1);
        return (string)( (integer)(i / f) ) + "." + llGetSubString( s, -places, -1);
    }
    if (!places)
        return (string)((integer)num );
    if ( (places = (places - 7 - (places < 1) ) ) & 0x80000000)
        return llGetSubString((string)num, 0, places);
    return (string)num;
