IEEE754 for Javascript

Javascript library to convert values to decimal format and vice versa with IEEE754 standard.

To do:

  • Code refactoring/optimizing
  • Rounding
  • Values under 1
  • Underflow
  • Overflow
  • Handling the rounding errors
  • Error catching
  • Catching wrong inputs
  • Some additional test with jest
  • Add default value if no options are passed
  • Add error handling if no value is passed

How to use

const ieee754 = require(./ieee754);
const optionsWithReturnType = {mode: 'single', returnType: '16bitArray'};
const optionsWithoutReturnType = {mode: 'single'};

// Examples
console.log(ieee754.getDecimal([17530, 8192]);
// --> 1000.5
console.log(ieee754.getPrecision(1000.5, optionsWithReturnType));
// --> [17530, 8192]
console.log(ieee754.getPrecision(1000.5, optionsWithoutReturnType));
// --> 01000100011110100010000000000000
console.log(ieee754.getDecimal([0, 0]);
// --> 0
console.log(ieee754.getPrecision(0, optionsWithReturnType));
// --> [0, 0]
console.log(ieee754.getPrecision(0, optionsWithoutReturnType));
// --> 00000000000000000000000000000000
