Functions ¶

func FortyTwo ¶

func FortyTwo(sig *types.Type, input []types.Value) (types.Value, error)

FortyTwo returns 42 as either an int or a float. This is not especially useful, but was built for a fun test case of a simple poly function with two different return types, but no input args.

func Minus1 ¶

func Minus1(ctx context.Context, input []types.Value) (types.Value, error)

Minus1 takes an int and subtracts one from it.

func Mod ¶

func Mod(ctx context.Context, input []types.Value) (types.Value, error)

Mod returns mod(x, y), the remainder of x/y. The two values must be either both of KindInt or both of KindFloat, and it will return the same kind. If you pass in a divisor of zero, this will error, eg: mod(x, 0) = NaN. TODO: consider returning zero instead of erroring?

func Pow ¶

func Pow(ctx context.Context, input []types.Value) (types.Value, error)

Pow returns x ^ y, the base-x exponential of y.

func Sqrt ¶

func Sqrt(ctx context.Context, input []types.Value) (types.Value, error)

Sqrt returns sqrt(x), the square root of x.
