epsicheck

Five simple utilities for comparing two floating point numbers, each with a short alias:

The default epsilon is 1e-6 and can be customized using the third parameter.

`a, b`	`eq(a, b)`	`lt(a, b)`	`lte(a, b)`	`gt(a, b)`	`gte(a, b)`
`1, 2`		:white_check_mark:	:white_check_mark:
`1, 1 + 1e-5`		:white_check_mark:	:white_check_mark:
`1, 1 + 1e-7`	:white_check_mark:		:white_check_mark:		:white_check_mark:
`1, 1`	:white_check_mark:		:white_check_mark:		:white_check_mark:
`1 + 1e-7, 1`	:white_check_mark:		:white_check_mark:		:white_check_mark:
`1 + 1e-5, 1`				:white_check_mark:	:white_check_mark:
`2, 1`				:white_check_mark:	:white_check_mark:

The above table is assuming the default epsilon of 1e-6.

$ npm i epsicheck

import { eq } from 'epsicheck'

console.assert(eq(0.1 + 0.2, 0.3))
console.assert(0.1 + 0.2 != 0.3)
