Javascript IEEE-754 converter

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
