Using math/big (Sqrt2) in Go
by GoDoc Go big.Float big.Float.SetPrec fmt.Printf big.Float.Add big.Float.Mul
This example shows how to use big.Float to compute the square root of 2 with a precision of 200 bits, and how to print the result as a decimal number.
RoundingMode in Go
by GoDoc Go big.Float fmt.Printf big.ToNearestEven big.ToPositiveInf fmt.Println
RoundingMode determines how a Float value is rounded to the desired precision. Rounding may change the Float value; the rounding error is described by the Float's Accuracy.
Float.Scan in Go
by GoDoc Go big.Float fmt fmt.Println fmt.Sscan log
Scan is a support routine for fmt.Scanner; it sets z to the value of the scanned number. It accepts formats whose verbs are supported by fmt.Scan for floating point values, which are: 'b' (binary), 'e', 'E', 'f', 'F', 'g' and 'G'. Scan doesn't handle ±Inf.
Float.Add in Go
by GoDoc Go big.Float fmt.Printf fmt math/big
Add sets z to the rounded sum x+y and returns z. If z's precision is 0, it is changed to the larger of x's or y's precision before the operation. Rounding is performed according to z's precision and rounding mode; and z's accuracy reports the result error relative to the exact (not rounded) result. ...
