mathjs v0.15.0 Release Notes

Release Date: 2013-10-26 // over 10 years ago
    • 👍 Math.js must be instantiated now, static calls are no longer supported. Usage:
      • node.js: var math = require('mathjs')();
      • browser: var math = mathjs();
    • 👍 Implemented support for multiplying vectors with matrices.
    • 👌 Improved number formatting:
      • Function format now support various options: precision, different notations (fixed, scientific, auto), and more.
      • Numbers are no longer rounded to 5 digits by default when formatted.

      • Removed option math.options.precision, use math.format(value [, precision]) instead.
      • Fixed formatting numbers as scientific notation in some cases returning a zero digit left from the decimal point. (like "0.33333e8" rather than "3.3333e7"). Thanks @husayt.
