Move the decimal point of numbers to the right or left, operating on the number as a string. In other words, a lightweight way to perform accurate division/multiplication with powers of 10 without needing a library for arbitrary-precision decimal arithmetic.
npm install move-decimal-point
var move_decimal = require('move-decimal-point');
// Move to the right
move_decimal('123.456', 1); // '1234.56'
move_decimal('123.456', 3); // '123456'
move_decimal('123.456', 5); // '12345600'
// Move to the left
move_decimal('123.456', -1); // '12.3456'
move_decimal('123.456', -3); // '0.123456'
move_decimal('123.456', -5); // '0.00123456'git clone [email protected]:shesek/move-decimal-point.git &&
