Binary String
Returns a string giving the literal bit representation of a single-precision floating-point number.
Installation
$ npm install math-float32-to-binary-string
Usage
var binaryString = ;
binaryString( x )
Returns a string
giving the literal bit representation of a single-precision floating-point number.
var toFloat32 = ;var str = ;// returns '01000000100000000000000000000000'str = ;// returns '01000000010010010000111111011011'str = ;// returns '11111110100101100111011010011001'
The function
handles subnormals.
str = ;// returns '10000000001000100011000100001011'str = ;// returns '00000000000000000000000000000001'
The function
handles special values.
var pinf = ;var ninf = ;str = ;// returns '00000000000000000000000000000000'str = ;// returns '10000000000000000000000000000000'str = ;// returns '01111111110000000000000000000000'str = ;// returns '01111111100000000000000000000000'str = ;// returns '11111111100000000000000000000000'

Tests
Unit
This repository uses tape for unit tests. To run the tests, execute the following command in the top-level application directory:
$ make test
All new feature development should have corresponding unit tests to validate correct functionality.
Test Coverage
This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:
$ make test-cov
Istanbul creates a ./reports/coverage
directory. To access an HTML version of the report,
$ make view-cov
Browser Support
This repository uses Testling for browser testing. To run the tests in a (headless) local web browser, execute the following command in the top-level application directory:
$ make test-browsers
To view the tests in a local web browser,
$ make view-browser-tests
