Examples using... "math/big"

Recent

by GoDoc Go math/big big.Float big.Float.SetPrec fmt.Printf big.Float.Add

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.

Using math/big (Fibonacci) in Go

by GoDoc Go math/big big.NewInt fmt.Println big.Int big.Int.Exp

This example demonstrates how to use big.Int to compute the smallest Fibonacci number with 100 decimal digits and to test whether it is prime.

Using math/big (EConvergents) in Go

by GoDoc Go math/big big.Rat big.Rat.SetInt64 big.Rat.Add big.Rat.Inv

This example demonstrates how to use big.Rat to compute the first 15 terms in the sequence of rational convergents for the constant e (base of natural logarithm).

RoundingMode in Go

by GoDoc Go math/big 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.

Rat.SetString in Go

by GoDoc Go math/big big.Rat big.Rat.FloatString big.Rat.SetString fmt

SetString sets z to the value of s and returns z and a boolean indicating success. s can be given as a (possibly signed) fraction "a/b", or as a floating-point number optionally followed by an exponent. If a fraction is provided, both the dividend and the divisor may be a decimal integer or independ...

Rat.Scan in Go

by GoDoc Go math/big big.Rat fmt fmt.Println fmt.Sscan

Scan is a support routine for fmt.Scanner. It accepts the formats 'e', 'E', 'f', 'F', 'g', 'G', and 'v'. All formats are equivalent.

Int.SetString in Go

by GoDoc Go math/big big.Int big.Int.SetString fmt fmt.Println

SetString sets z to the value of s, interpreted in the given base, and returns z and a boolean indicating success. The entire string (not just a prefix) must be valid for success. If SetString fails, the value of z is undefined but the returned value is nil.

Int.Scan in Go

by GoDoc Go math/big big.Int fmt fmt.Println fmt.Sscan

Scan is a support routine for fmt.Scanner; it sets z to the value of the scanned number. It accepts the formats 'b' (binary), 'o' (octal), 'd' (decimal), 'x' (lowercase hexadecimal), and 'X' (uppercase hexadecimal).

Float.Scan in Go

by GoDoc Go math/big big.Float fmt fmt.Println fmt.Sscan

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.Cmp in Go

by GoDoc Go math/big fmt.Println big.NewFloat fmt fmt.Printf

Cmp compares x and y and returns:

Float.Add in Go

by GoDoc Go math/big fmt.Printf big.Float fmt

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. ...

Float (Shift) in Go

by GoDoc Go math/big big.NewFloat fmt fmt.Println

A nonzero finite Float represents a multi-precision floating point number
