meters to feet and inches conversion

I have this code to tell how tall an avatar is:

default {
touch_start(integer num_detected) {
vector size;

size = llGetAgentSize(llDetectedKey(0));
size = size * 39;
size = size /12;
llSay(0, "You are " + (string)size.z + " feet tall.";

//Rotate the texture - all sides of the prim
llSetTextureAnim(ANIM_ON | SMOOTH | LOOP | ROTATE,
ALL_SIDES, 8, 1, 0, 7, .1);

}
}

It currently returns a string like You are 5.8884527 feet tall. I want it to say you are 5 feet 3 inches tall...

Can someone help me with the math I need to do this?

Thanks

You could take the decimal part (perhaps by subtracting the integer portion of the number) and multiply it by 12. That would give you the inches. Then convert that to an integer again.

I would change this:

size = llGetAgentSize(llDetectedKey(0));
size = size * 39;
size = size /12;
llSay(0, "You are " + (string)size.z + " feet tall.";

to the following:

sizeCM = llGetAgentSize( llDetectedKey( 0 ) ) / 100;
sizeIn = sizeCM.z / 2.54;
sizeFt = (integer) (sizeIn / 12);
sizeIn = sizeIn - sizeFt;

llSay( 0, "You are " + (string) sizeFt + " feet, " + (string) sizeIn + " inches tall." );

This brings up one of my personal hobbyhorses, namely the imminent death of the metric system. It seems to me that with the advent of calculators and computers, the metric system will be returned to the dustbin of history from whence it came. Beyond complex computation, the advantages of the Imperial English system are so manifest that it won't be long before this Napoleonic flash-in-the-pan simply dies out from lack of popular mind-share.

Considering that SL is presumably aimed at a futurist clientelle, it's use of the metric system seems at best ill considered.

Base 12 vs Base 10... since I grew up learning base 10, and heaven forbid we should have it so easy with 1cm^3 = 1 mL

vector Size = llGetAgentSize( llDetectedKey(0) ) / 0.3048;
integer Feet = Size.z;
integer Inches = llRound( Size.z * 12 ) % 12;

Results rounded to nearest inch.

Thanks for all your help! I sort of took a hodge podge of the suggestions and came up with this:

default {
touch_start(integer num_detected) {


vector size = llGetAgentSize( llDetectedKey( 0 ) ) / 0.3048;
float sizeFT = size.z ;
sizeFT =llRound (sizeFT);
integer Inches = llRound( size.z * 12 ) % 12;

llSay( 0, "You are " + (string) sizeFT + " feet, "+ (string)Inches +" inches tall." );

The output is You are 6.000000 feet, 9 inches tall.

Actually, I see that rounding the sizeFT is not what I want it to do either. Lets say the value in meters is 1.757527. When I convert that to feet I get 5.741469. I want the output to be 5 feet, 7 inches.

BTW...I am very new to coding..this is the first script I have tried to tweak on my own. I appreciate any and all help!
THanks

Looks pretty close; I think you just want integer sizeFT = (integer)size.z instead of llRound()ing it.

Haha, that is really funny, must surely be tongue in cheek.
Otherwise one can only presume that you must be US based and it has somehow escaped your notice that rest of the world doesn't reside in the US which is the last bastion of of the anachronistic Imperial system.
SL aimed at a global market, very sensibly decided to choose the metric system which is used and understood by the rest of the world.

AH HA! That did it. Thank yo uso much
