		<h2>Methods</h2>

		<h3>[method:Number toHalfFloat]( [param:Number val] )</h3>
		<p>
			val -- A single precision floating point value.<br /><br />

			Returns a half precision floating point value from the given single
			precision floating point value.
		</p>

		<h3>[method:Number fromHalfFloat]( [param:Number val] )</h3>
		<p>
			val -- A half precision floating point value.<br /><br />

			Returns a single precision floating point value from the given half
			precision floating point value.
		</p>


		<h3>[method:Uint32Array toRGB9E5]( [param:Number r], [param:Number g], [param:Number b], [param:Uint32Array target] )</h3>
		<p>
			r -- A float representing the R channel.<br />
			g -- A float representing the G channel.<br />
			b -- A float representing the B channel.<br />
			target -- An instance of `Uint32Array` with length `1`.<br /><br />

			This method packs three floats into a single Uint32 value which is required for the `RGB9E5` texture format.
		</p>

		<h3>[method:Array fromRGB9E5]( [param:Uint32Array val], [param:Array target] )</h3>
		<p>
			val -- An instance of `Uint32Array` with length `1`.<br />
			target -- An array holding the three unpacked floats.<br /><br />

			This method unpacks three floats from a single Uint32 value holding a `RGB9E5` texel.
