New to generics... how can I write a method for a Matrix[float64] that uses
a math function that expects a float64? I get:
./slurp1.go:936:18: cannot use m.At(i, j) (value of type float64
constrained by Addable) as float64 value in argument to math.IsNaN
Casting it to float64() does not change this error(!)
here is the essentials:
type Addable interface {
~complex128 | ~complex64 | ~float64 | ~float32 |
~byte | ~uint16 | ~uint32 | ~uint64 |
~int8 | ~int16 | ~int32 | ~int64 | ~int
}
type Matrix[T Addable] struct {
Nrow int
Ncol int
Dat []T
}
...
func (m *Matrix[float64]) NanToZero() {
for i := 0; i < m.Nrow; i++ {
for j := 0; j < m.Ncol; j++ {
if math.IsNaN(m.At(i, j)) { // line 936, where the error is;
./slurp1.go:936:18: cannot use m.At(i, j) (value of type float64
constrained by Addable) as float64 value in argument to math.IsNaN
m.Set(i, j, 0)
}
}
}
}
go version go1.20.6 linux/amd64
