Overview

Package numbers provide miscellaneous functions for working with integer and float.

Index

• func Float64Round(v float64, nprec int) float64
• func Int64CreateSeq(min, max int64) (seq []int64)
• func IntCreateSeq(min, max int) (seq []int)
• func IntPickRandPositive(maxVal int, dup bool, pickedListID, exsListID []int) (idx int)

Functions

func Float64Round

func Float64Round(v float64, nprec int) float64

Float64Round will round `v` to `nprec` digit in fraction.

func Int64CreateSeq

func Int64CreateSeq(min, max int64) (seq []int64)

Int64CreateSeq will create and return sequence of integer from `min` to `max`.

E.g. if min is 0 and max is 5 then it will return `[0 1 2 3 4 5]`.

func IntCreateSeq

func IntCreateSeq(min, max int) (seq []int)

IntCreateSeq will create and return sequence of integer from `min` to `max`.

E.g. if min is 0 and max is 5 then it will return `[0 1 2 3 4 5]`.

func IntPickRandPositive

func IntPickRandPositive(maxVal int, dup bool, pickedListID, exsListID []int) (idx int)

IntPickRandPositive return random integer value from 0 to maximum value `maxVal`.

The random value is checked with already picked index: `pickedListID`.

If `dup` is true, allow duplicate value in `pickedListID`, otherwise only single unique value allowed in `pickedListID`.

If excluding index `exsListID` is not empty, do not pick the integer value listed in there.
