You could use math.floor(x) From the Lua Reference Manual: Returns the largest integer smaller than or equal to x.

Division of integers in Java
Converting the output is too late; the calculation has already taken place in integer arithmetic. You need to convert the inputs to double: Note that you don’t actually need to convert both of the inputs. So long as one of them is double, the other will be implicitly converted. But I prefer to do both, for symmetry.
why f is placed after float values?
by default 12.3 is double literal, So to tell compiler to treat it as float explicitly -> it uses f or F
Printf width specifier to maintain precision of floating-point value
I recommend @Jens Gustedt hexadecimal solution: use %a. OP wants “print with maximum precision (or at least to the most significant decimal)”. A simple example would be to print one seventh as in: But let’s dig deeper … Mathematically, the answer is “0.142857 142857 142857 …”, but we are using finite precision floating point numbers. … Read more
Using floats with sprintf() in embedded C
Since you’re on an embedded platform, it’s quite possible that you don’t have the full range of capabilities from the printf()-style functions. Assuming you have floats at all (still not necessarily a given for embedded stuff), you can emulate it with something like: You’ll need to restrict how many characters come after the decimal based … Read more
What do F and D mean at the end of numeric literals?
Means that these numbers are doubles and floats, respectively. Assume you have and then you call the compiler might be stumped. That’s why you can say 5, 5f, or 5.0 to specify the type.
How to parse float with two decimal places in javascript?
You can use toFixed() to do that
Dealing with float precision in Javascript
From this post: How to deal with floating point number precision in JavaScript? You have a few options: Use a special datatype for decimals, like decimal.js Format your result to some fixed number of significant digits, like this: (Math.floor(y/x) * x).toFixed(2) Convert all your numbers to integers
Python: Converting string into decimal number
If you want the result as the nearest binary floating point number use float: If you want the result stored exactly use Decimal instead of float:
Float and double datatype in Java
The Wikipedia page on it is a good place to start. To sum up: float is represented in 32 bits, with 1 sign bit, 8 bits of exponent, and 23 bits of the significand (or what follows from a scientific-notation number: 2.33728*1012; 33728 is the significand). double is represented in 64 bits, with 1 sign bit, 11 bits of … Read more
