7,824 PointsJavaScript doesn't seem fit to parse the "decimals" of octimal numbers, i.e. the numbers after the point. Thoughts?
I would like to hear if there are ways around this problem, or whether it is in fact a limitation of the JS language.
To specify what is going on. Instead of parsing the string as an octimal number, the following code:
console.log(parseFloat("10.135", 8));
just returns 10.135. If I enter the following code:
console.log(010.135);
the return reads: "Uncaught SyntaxError: Unexpected number"
So, am I correct in concluding that JS cannot work with non-ten-based numbers in "decimals".

14,346 PointsThe parseFloat() function parses a string and returns a floating point number.
This function determines if the first character in the specified string is a number. If it is, it parses the string until it reaches the end of the number, and returns the number as a number, not as a string.
Note: Only the first number in the string is returned!
Note: Leading and trailing spaces are allowed.
Note: If the first character cannot be converted to a number, parseFloat() returns NaN or in other words this error "Uncaught SyntaxError: Unexpected number".
console.log(010.135);
Uncaught SyntaxError: Unexpected number
console.log(parseFloat("010.135"));
10.135
Hopefully this gives a better understanding of how JavaScript interprets numbers and decimal numbers. http://www.w3schools.com/jsref/jsref_parsefloat.asp

14,346 PointsYes, when using console.log(010.135); JavaScript can't work with non-ten-based numbers, it can only work if you use syntax from the above post.
