math.Pow() Function in Golang With Examples

func Pow(a, b float64) float64

• If Pow(a, ±0), then this method will return 1 for any a.
• If Pow(1, b), then this method will return 1 for any b.
• If Pow(a, 1), then this method will return a for any a.
• If Pow(NaN, b), then this method will return NaN.
• If Pow(a, NaN), then this method will return NaN.
• If Pow(±0, b), then this method will return ± Inf for b an odd integer < 0.
• If Pow(±0, -Inf), then this method will return +Inf.
• If Pow(±0, +Inf), then this method will return +0.
• If Pow(±0, b), then this method will return +Inf for finite b < 0 and not an odd integer.
• If Pow(±0, b), then this method will return ± 0 for b an odd integer > 0.
• If Pow(±0, b), then this method will return +0 for finite b > 0 and not an odd integer.
• If Pow(+1, ±Inf), then this method will return 1.
• If Pow(a, +Inf), then this method will return +Inf for |a| > 1.
• If Pow(a, -Inf), then this method will return +0 for |a| > 1.
• If Pow(a, +Inf), then this method will return +0 for |a| < 1.
• If Pow(a, -Inf), then this method will return +Inf for |a| < 1.
• If Pow(+Inf, b), then this method will return +Inf for b > 0.
• If Pow(+Inf, b), then this method will return +0 for b < 0.
• If Pow(-Inf, b), then this method will return Pow(-0, -b).
• If Pow(a, b), then this method will return NaN for finite a < 0 and finite non-integer b.
