Convert a Float number to an Int type

I am trying to convert a float number to an integer. The reason is that I want the E8S equivalent of 1 ICP of a value, for example 1.15. This should be 115_000_000, but the function returns 114_000_000. Other values are calculated correctly, for example 1.25 = 125_000_000 or 0.9 = 90_000_000. ... More on forum.dfinity.org

math - Safest way to convert float to integer in python? - Stack Overflow

Indeed, both round and floor return integers in Python 3.x. So I suppose that the question concerns Python 2.x. 2010-08-02T12:40:10.67Z+00:00 ... why does round(6.5) gives 6? It seems to kinda ceil() the float when there's an immediate 5 (or greater up to 9) after the decimal in all other cases. Why is this not working in this case? or any other case when the number ends with a six and there's a 5 right after the decimal... 2017-07-22T09:02:16.437Z+00:00 ... This converts ...

math - Safest way to convert float to integer in python? - Stack Overflow

All integers that can be represented by floating point numbers have an exact representation. So you can safely use int on the result. Inexact representations occur only if you are trying to represent a rational number with a denominator that is not a power of two.

That this works is not trivial at all! It's a property of the IEEE floating point representation that int∘floor = ⌊⋅⌋ if the magnitude of the numbers in question is small enough, but different representations are possible where int(floor(2.3)) might be 1.

To quote from Wikipedia,

Any integer with absolute value less than or equal to 2²⁴ can be exactly represented in the single precision format, and any integer with absolute value less than or equal to 2⁵³ can be exactly represented in the double precision format.

Use int(your non integer number) will nail it.

print int(2.3) # "2"
print int(math.sqrt(5)) # "2"

Danger in Floating-Point-to-Integer Conversion

The natural way to implement the conversion is to scale each floating point sample to some appropriate range (-32767 to 32767) and assign it to a signed 16-bit integer as follows: float f; /* assume -32768 <= f <= 32767 */ int i; /* could also be “shortint” */ i = (int) f; /* “(int) f” means “convert f to an int” */ The default float-to-integer conversion in C does not round to the nearest integer, but instead truncates toward zero.

floating point - How to convert float to int with Java - Stack Overflow

Using Math.round() will round the float to the nearest integer.

Actually, there are different ways to downcast float to int, depending on the result you want to achieve: (for int i, float f)

round (the closest integer to given float)

i = Math.round(f);
  f =  2.0 -> i =  2 ; f =  2.22 -> i =  2 ; f =  2.68 -> i =  3
  f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -3

note: this is, by contract, equal to (int) Math.floor(f + 0.5f)

truncate (i.e. drop everything after the decimal dot)

i = (int) f;
  f =  2.0 -> i =  2 ; f =  2.22 -> i =  2 ; f =  2.68 -> i =  2
  f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -2

ceil/floor (an integer always bigger/smaller than a given value if it has any fractional part)

i = (int) Math.ceil(f);
  f =  2.0 -> i =  2 ; f =  2.22 -> i =  3 ; f =  2.68 -> i =  3
  f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -2

i = (int) Math.floor(f);
  f =  2.0 -> i =  2 ; f =  2.22 -> i =  2 ; f =  2.68 -> i =  2
  f = -2.0 -> i = -2 ; f = -2.22 -> i = -3 ; f = -2.68 -> i = -3

For rounding positive values, you can also just use (int)(f + 0.5), which works exactly as Math.Round in those cases (as per doc).

You can also use Math.rint(f) to do the rounding to the nearest even integer; it's arguably useful if you expect to deal with a lot of floats with fractional part strictly equal to .5 (note the possible IEEE rounding issues), and want to keep the average of the set in place; you'll introduce another bias, where even numbers will be more common than odd, though.
