Static methods

@:value({ maxDifference : 0.000001 })staticfuzzyEquals(n1:Float, n2:Float, maxDifference:Float = 0.000001):Bool

Compares two Float values in a way that they are considered equal if their difference is below a certain threshold. Useful for meaningful comparisons between numbers that may be slightly different due to floating point errors.

Parameters:

n1

the first number to compare

n2

the second number to compare

maxDifference

the maximum difference between the two numbers to be considered equal

Returns:

true if the numbers are considered equal

@:value({ nearest : 1.0 })staticroundDownToNearest(number:Float, nearest:Float = 1.0):Float

Rounds a number down to the nearest multiple of an input. For example, by rounding 16 down to the nearest 10, you will receive 10, and by rounding 26 down to the nearest 10, you will receive 20. Similar to the built-in function Math.floor().

Parameters:

numberToRound

the number to round down

nearest

the number whose mutiple must be found

Returns:

the rounded number

@:value({ nearest : 1.0 })staticroundToNearest(number:Float, nearest:Float = 1.0):Float

Rounds a number to the nearest multiple of an input. For example, by rounding 26 to the nearest 10, you will receive 30, and by rounding 24 to the nearest 10, you will receive 20. Similar to the built-in function Math.round().

Parameters:

numberToRound

the number to round

nearest

the number whose mutiple must be found

Returns:

the rounded number

@:value({ precision : 0 })staticroundToPrecision(number:Float, precision:Int = 0):Float

Rounds a number to a certain level of decimal precision. Useful for limiting the number of decimal places on a fractional number.

Parameters:

number

the input number to round.

precision

the number of decimal digits to keep

Returns:

the rounded number, or the original input if no rounding is needed

@:value({ nearest : 1.0 })staticroundUpToNearest(number:Float, nearest:Float = 1.0):Float

Rounds a number up to the nearest multiple of an input. For example, by rounding 16 up to the nearest 10, you will receive 20, and by rounding 26 up to the nearest 10, you will receive 30. Similar to the built-in function Math.ceil().

Parameters:

numberToRound

the number to round up

nearest

the number whose mutiple must be found

Returns:

the rounded number
