Method SetFloat64

decimal.go:249–253

SetFloat64 sets d's Coefficient and Exponent to x and returns d. d will hold the exact value of f.

(f float64)

// SetFloat64 sets d's Coefficient and Exponent to x and returns d. d will
// hold the exact value of f.
func (d *Decimal) SetFloat64(f float64) (*Decimal, error) {
	var buf [32]byte // Avoid most of the allocations in strconv.
	_, _, err := d.SetString(string(strconv.AppendFloat(buf[:0], f, 'E', -1, 64)))
	return d, err
}

// Int64 returns the int64 representation of x. If x cannot be represented in an
// int64, an error is returned.
