Calculate addition, subtraction, multiplication, and division precisely using JS
0.1 + 0.2 = 0.30000000000000004
1.0 - 0.9 = 0.09999999999999998
1.1 * 1.1 = 1.2100000000000002
1.21 / 1.1 = 1.0999999999999999npm install --save number-calc
NC.add(number1, number2) // addition, number1 + number2
NC.subtract(number1, number2) // subtraction, number1 - number2
NC.multiply(number1, number2) // multiplication, number1 * number2
NC.divide(number1, number2) // division, number1 / number2
NC.prune(number, precision) // prune, precision defaults to 12import NC from 'number-calc'
