Float2String

Function notes

Negative floats are fine (i.e. negative signs will be preserved.)

If you say 1 place, you will get 7.0 instead of 7.0000000

If you say 3 places, you get 7.14 instead of 7.1400000

7.1373699 will come out as 7.13 or 7.14, depending on whether you specify rounding

rnd (rounding) should be set to TRUE for Rounding, FALSE for no rounded

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"

Return value notes

Returns a string that contains the float num in a tidy text format, with optional rounding.

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;
