big.Int supports both Division and Modulo operations. Why division and modulo operations are not supported in big.Float? Is Quo() is different from division? Is there math.Mod(x, y float64) equivalent for big.Float
Division or quotient operation on integers and big integers produce integer value while on floats it produce float. That's why operations have different precision and mathematical sense.
var x, y int = 5, 3
z:=x/y //give you 1
but
var x, y float32 = 5, 3
z:=x/y //give you 1.6666666
Modulo or reminder operations didn't defined on floats because it's hard to elaborate what them can mean. Same with math/big
