my_var = (int)my_var;
As simple as that. Basically you don't need it if the variable is int.

Convert a Float number to an Int type - Developers - Internet Computer Developer Forum
June 10, 2024 - 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. public func convertFloatToNat(x: Float): async Int { let ONE_ICP_IN_E8S = 100_000_000; Debug.print("convertFloatToNat "#debug_show(x)); let a = x * 100; Debug.print("float x 100 = "#...

C++ Float to Int Conversion (How To Guide) | by ryan | Medium
January 7, 2025 - In this example, we use `std::round` to convert the floating-point position to pixel coordinates. This ensures the ball is drawn at the nearest pixel, providing smooth animation. When working with financial calculations, using floats can lead to rounding errors. Consider this seemingly simple calculation: float price = 19.99f; int cents = static_cast<int>(price * 100); // Expect 1999, but might get 1998!

Type conversion: Floating-point and integer
The floating-point to integer conversion operator converts the given float operand to a signed or unsigned integer data type. In practice, the conversion is performed in two steps. First the floating-point value is rounded to the next lower integer value.

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.

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 = -3note: 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 = -2ceil/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.

r/cpp on Reddit: Converting float to int can be undefined behavior and how to fix it
December 31, 2021 - All of these conversions are undefined behavior if the float is out of bounds for the int. [0] This is surprising, easy to miss and badly designed as there is no standard way of safely performing this conversion. In practice you will get an unspecified int because compilers emit the corresponding converting assembly instruction but UB is still bad and should be avoided.

March 12, 2018 - Java allows you to cast, or convert a variable of one type to another; in this case, cast a float to an int. This option removes all digits to the right of the decimal place. Another option is to use the Math.round method to round the value to the nearest integer.
