List of functions

• Math::Ldexp(Double{Flags:AutoMap}, Int32{Flags:AutoMap}) -> Double
• Math::Round(Double{Flags:AutoMap}, [Int32?]) -> Double: The second argument indicates the power of 10 to which we round (it’s negative for decimal digits and positive for rounding to tens, thousands, or millions); the default value is 0

(Double, Double, [Double?]) -> Bool

List of functions

• Math::FuzzyEquals(Double{Flags:AutoMap}, Double{Flags:AutoMap}, [Double?]) -> Bool: Compares two Doubles for being inside the neighborhood specified by the third argument; the default value is 1.0e-13

Examples

SELECT Math::FuzzyEquals(1.01, 1.0, 0.05); -- true

List of functions

• Math::Rem(Int64{Flags:AutoMap}, Int64) -> Int64?

These functions behave similarly to the built-in % operator in the case of non-negative arguments. The differences are noticeable in the case of negative arguments:

• Math::Mod preserves the sign of the second argument (the denominator).
