Livecode's math precision

[Peter W A Wood]

Mike

This explanation from Mark Waddingham confirms that numbers are held in IEEE 754 format - http://quality.runrev.com/show_bug.cgi?id=9349

I’m pretty sure it is 64-bit. I tried multiplying a value of Pi with more significant digits than a 32 bit number can hold in the message box:

Code:
	put format ("%.30g",3.14159265358979323846264338327950 * 1.0)

Result:
	3.14159265358979311599796346854

Hope this helps

Peter
