need a little help converting a float var to a .ToString

Questions & Answers
1

I know there is a way to do it, but i can not remember and i can not find the info anywhere that would help me. I saw a few examples but none were what i needed
mainly it is the last line of code. i want to convert the variable batteryLife to a string, but that line with batteryLife.ToString gives me an error.

thanks

#pragma strict
var batteries: float = 2.0f;
var batteryLife: float = 420.0f;
var batteryReductionSpeed: float = 1.0f;

var lightRange: float = 100.0f;

var verticalOffset01: float = 0.47f;

var horizontalOffset02: float = 0.37f;
var verticalOffset02: float = 0.4f;

var horizontalOffset03: float = 0.37f; //701
var verticalOffset03: float = -100f;    // 0.72

//var guiLifeOfBattery = guiText;

GUI.Label accepts only one string parameter, thus you must concatenate what you want to show in a single string. Furthermore, ToString is a function: ToString() displays the value in a default format, while ToString(“F2”) - for instance - displays the value with two decimals. Your code should be something like this:

GUI.Label(Rect (...), "Battery Life Remaining: "+batteryLife.ToString());

Another approach is to just concatenate the numeric value to a string - ToString() is internally called by the compiler in such cases:

GUI.Label(Rect (...), "Battery Life Remaining: "+batteryLife);
