Functions ¶

func DivideCeil ¶

func DivideCeil(count int64, pageSize int64) int64

DivideCeil divides two integers and rounds up, rather than down (which is what happens when you do int64/int64).

func IsSignedZero ¶

func IsSignedZero(f float64) bool

IsSignedZero checks if this number is a signed zero (i.e. -0, instead of +0).

func Limit ¶

func Limit(v, lower, upper float64) float64

Limit a value between a lower and upper limit.

func Max ¶

func Max(a, b int64) int64

Max gets the highest of two numbers.

func Min ¶

func Min(a, b int64) int64

Min gets the lowest of two numbers.

func Round ¶

func Round(f float64) float64

Round will round the value to the nearest natural number.

.5 will be rounded up.

func RoundPlus ¶

func RoundPlus(f float64, precision int) float64

RoundPlus will round the value to the given precision.

e.g. RoundPlus(7.258, 2) will return 7.26

Types ¶

type Byte ¶

type Byte float64

Byte is a float64 where the String() method prints out a human-redable description.

func (Byte) HumanReadable ¶

func (b Byte) HumanReadable(measurement Byte, format []string) string

HumanReadable will take a measurement multiple as well as a slice of formats to convert the byte into a human readable format using the given parameters.

func (Byte) String ¶

func (b Byte) String() string

String will return the bytes formatted as "mebibytes" (multiples of 1024)

func (Byte) StringAsBytes ¶

func (b Byte) StringAsBytes() string

StringAsBytes will return the bytes formatted as "bytes" (multiples of 1000)
