func AbsI64 ¶

func AbsI64(val int64) int64

Return the absolute value of a 64-bit signed integer value.

func ClampI64 ¶

func ClampI64(val, minVal, maxVal int64) int64

Clamp a signed 64-bit value to a minima and maxima.

func FormatFloat64 ¶

func FormatFloat64(num float64) string

Format a float.

If the float is NaN or infinite, then those are explicitly returned.

func MaxI ¶

func MaxI(lhs, rhs int) int

Return the maximum value of the integer values.

func MaxI32 ¶

func MaxI32(lhs, rhs int32) int32

Return the maximum value of the 32-bit integer values.

func MaxI64 ¶

func MaxI64(lhs, rhs int64) int64

Return the maximum value of the 64-bit integer values.

func MinI ¶

func MinI(lhs, rhs int) int

Return the minimum value of the integer values.

func MinI32 ¶

func MinI32(lhs, rhs int32) int32

Return the minimum value of the 32-bit integer values.

func MinI64 ¶

func MinI64(lhs, rhs int64) int64

Return the minimum value of the 64-bit integer values.

func RoundF ¶

func RoundF(num float64, precision uint) float64

Rounds num to the given number of decimal places and returns the result as a float64, using math.Round for IEEE-754 compliant rounding.

func RoundI ¶

func RoundI(num float64) int

Rounds a 64-bit floating point number to the nearest integer, returning it as an int. Values halfway between integers are rounded away from zero.

func ToFixed ¶

func ToFixed(num float64, precision uint) float64

Rounds num to the given number of decimal places and returns the result as a float64. Unlike RoundF, it uses integer rounding logic (via RoundI), which may behave slightly differently around half-values.

func WithinPlatform ¶

func WithinPlatform(value, defValue int64) int

Ensure that the given value is within the limit of the platform-specific integer type and, if it is, multiply it by two.

If the value would be larger than the platform integer, then the default value in `defValue` is returned.

If `defValue` is too large, then the maximum integer size for the platform is returned.
