NewFloat16FromString returns a new 16-bit floating-point value based on s, which contains 4 bytes in hexadecimal format.
func (Float16) Bytes ¶
Bytes returns the IEEE 754 binary representation of f as a byte slice, containing 4 bytes in hexadecimal format.
type Float80 ¶
type Float80 struct {
// contains filtered or unexported fields
}
Float80 represents an 80-bit IEEE 754 extended precision floating-point value, in x86 extended precision format.
