power(_:_:)

func power(_ base: any EcoreValue, _ exponent: any EcoreValue) throws -> any EcoreValue

Return Value

The result of base raised to the power of exponent

Discussion

Computes the power operation as defined in OCL specification. Supports all numeric types with appropriate type coercion. Result type follows OCL rules: if either operand is Real, result is Real; otherwise Integer.

Type Coercion Rules

• Integer ^ Integer → Integer (if result fits in ELong range)

• Real ^ Any → Real

• Any ^ Real → Real

• Large integer results promote to EBigInteger

Examples

let result1 = try power(2 as EInt, 3 as EInt)        // Result: 8 as EInt
let result2 = try power(2.5 as EDouble, 2 as EInt)   // Result: 6.25 as EDouble
let result3 = try power(4 as EInt, 0.5 as EDouble)   // Result: 2.0 as EDouble
