almostEqual
[JVM]
open fun almostEqual(nSignificantDigits: Int, d1: Double, d2: Double): Boolean
This tests if the numbers are equal to at least n significant digits.
- Numbers must match to 1 part in 10^n to ensure that rounding to n-1 digits is identical.
- If d1 and d2 are almost0, this returns true.
- This is slow compared to almost0.
Return
true if the numbers are equal to at least n significant digits (or are both almost0). If either number is NaN or Infinity, this returns false.
Parameters
JVM
| nSignificantDigits | 0 to 18 are allowed; 5, 9, and 14 are common |
| d1 | any double |
| d2 | any double |
[JVM]
open fun almostEqual(nSignificantDigits: Int, f1: Float, f2: Float): Boolean
This tests if two floats are equal to at least n significant digits.
Return
true if the numbers are equal to at least n significant digits (or are both almost0). If either number is NaN or Infinity, this returns false.
Parameters
JVM
| nSignificantDigits | 0 to 18 are allowed; 5, 9, and 14 are common |
| f1 | any float |
| f2 | any float |
