I try to migrate from Python to Golang. I currently do research some math operations and wonder about how can I get both quotient and remainder value with result of a division. I'm going to share below an equivalent of Python code.
hours, remainder = divmod(5566, 3600)
minutes, seconds = divmod(remainder, 60)
print('%s:%s' % (minutes, seconds))
# 32:46
Above will be my aim. Thanks.
if you want a one-liner,
quotient, remainder := numerator/denominator, numerator%denominator
If you have a 32 bit number, you can use one of these:
package main
import "math/bits"
func main() {
{ // example 1
var n uint = 4294967295
q, r := bits.Div(0, n, 2)
println(q == n / 2, r == 1)
}
{ // example 2
var n uint32 = 4294967295
q, r := bits.Div32(0, n, 2)
println(q == n / 2, r == 1)
}
}
If you have a 64 bit number, you can do it like this:
package main
import "math/bits"
func main() {
var n uint64 = 18446744073709551615
q, r := bits.Div64(0, n, 2)
println(q == n / 2, r == 1)
}
If you have something larger than 64 bit, you can do it like this:
package main
import "math/bits"
func main() {
q, r := bits.Div64(1, 0, 2)
println(q == 9223372036854775808, r == 0)
}
I did this function maybe it's what you are looking for.
//QuotientAndRemainderF32 Computes the integer quotient and the remainder of the inputs. This function rounds floor(x/y) to the nearest integer towards -inf.
func QuotientAndRemainderF32(x, y float32) (Remainder, Quotient float32) {
Quotient = float32(math.Floor(float64(x / y)))
Remainder = x - y*Quotient
return Remainder, Quotient
}
