floats

Documentation

Overview

Package floats provides utilities for floating-point comparisons with epsilon tolerance to handle precision issues.

Usage

if floats.Equal64(0.1+0.2, 0.3) {
    // Handles floating-point precision issues
}

Functions

func Compare32

func Compare32(a, b float32, epsilon ...float32) int

Compare32 compares two float32 values with epsilon tolerance. Returns -1 if a < b, 0 if a == b (within epsilon), 1 if a > b.

func Compare64

func Compare64(a, b float64, epsilon ...float64) int

Compare64 compares two float64 values with epsilon tolerance. Returns -1 if a < b, 0 if a == b (within epsilon), 1 if a > b. An optional custom epsilon can be provided.

func Equal32

func Equal32(a, b float32, epsilon ...float32) bool

Equal32 checks if two float32 values are equal within epsilon tolerance.

func Equal64

func Equal64(a, b float64, epsilon ...float64) bool

Equal64 checks if two float64 values are equal within epsilon tolerance.

func IsZero32

func IsZero32(a float32, epsilon ...float32) bool

IsZero32 checks if a float32 value is zero within epsilon tolerance.

func IsZero64

func IsZero64(a float64, epsilon ...float64) bool

IsZero64 checks if a float64 value is zero within epsilon tolerance.
