Add methods with f64 std equivelant to Math object

[Nickforall]

I implemented some more Math functions which already have an equivelant in the rust standard library. There are still a couple more that have to be implemented, but they require a bit more work as they have some side effects or are not in the rust standard library. Those are out of scope for this PR.

List of Math object functions

• Math.abs()
• Math.acos()
• Math.acosh()
• Math.asin()
• Math.asinh()
• Math.atan()
• Math.atan2()
• Math.atanh()
• Math.cbrt()
• Math.ceil()
• Math.clz32()
• Math.cos()
• Math.cosh()
• Math.exp()
• Math.expm1()
• Math.floor()
• Math.fround()
• Math.hypot()
• Math.imul()
• Math.log()
• Math.log10()
• Math.log1p()
• Math.log2()
• Math.max()
• Math.min()
• Math.pow()
• Math.random()
• Math.round()
• Math.sign()
• Math.sin()
• Math.sinh()
• Math.sqrt()
• Math.tan()
• Math.tanh()
• Math.trunc()

Hey this is awesome, thanks!
will take a look (sorry ive been a while)

[jasonwilliams]

@Nickforall looks ok, are you planning to add tests for these?

Some errors

Math.acosh(0.999999999999);
// expected output: NaN

ParsingError: Expected token 'identifier', got '999999999999' in routine 'field access' at line 1, col 14
error: process didn't exit successfully: `target\debug\boa_cli.exe` (exit code: 1)
The terminal process terminated with exit code: 1

Math.atanh(0.5);
// // expected output: 0.549306144334055 (approximately)

ParsingError: Expected token 'identifier', got '5' in routine 'field 
access' at line 1, col 14
error: process didn't exit successfully: `target\debug\boa_cli.exe` (exit code: 1)
The terminal process terminated with exit code: 1

Looks like its not dealing with decimals properly.
Might be worth taking a look https://github.com/jasonwilliams/boa/blob/master/docs/debugging.md

decimal number parsing is a bit messed up, only if 0 is the first number
Token output for Math.atanh(0.5);

Commented and tested

[Nickforall]

Yeah sure, I’ll add some tests when i have time later this week :)

We have mini-test suite for lexing numbers, looks like 0.1 should be added:
https://github.com/jasonwilliams/boa/blob/master/boa/src/syntax/lexer/tests.rs#L384-L405

[Nickforall]

Will rebase once #272 is merged.

[Nickforall]

Rebased and added test for all methods. The tests are largely based on the docs from Mozilla

[jasonwilliams]

Thanks for your contribution @Nickforall it looks good
