Why do you have to wrap parenthesis around a number to called toFixed on it?
twig convert string to integer
twig number format thousands separator
twig number format leading zeros
unknown "format_currency" filter.
twig float to int
1.toFixed(2) // Uncaught SyntaxError: Invalid or unexpected token (1).toFixed(2) // "1.00" let num = 1 num.toFixed(2) // "1.00"
At the same time, you don't have to wrap parenthesis around strings to call methods on them
'yo'.repeat(3) // "yoyoyo"
What is the rule at play here and where else does it apply? Guessing it has something to do with the dot being misinterpreted as a decimal for numbers?
Because the interpreter is looking for more digits (decimal values), not keywords or methods.
1.2 and it doesn't like that
t there, it's not a number.
Interestingly, you can do this without parenthesis or making variable by using 2 decimal points. Like this:
1..toFixed(2). I guess you can also do
1.0.toFixed(2) if you want.
UDACITY quiz help, hi guys I am stucked in a udacity quiz,and no one helps me around their forum. Quiz: Out to Dinner (2-10) Create a variable called bill and assign it the result To use toFixed() pass it the number of decimal points you want to use. You don't have to recompute the sum in the tip; you can just use the value I get the whole redundancy thing. People make mistakes, it came from a time when people hand-wrote everything, etc. Why have 1 bridge across a river if you can have 2? But you have to draw the line somewhere. Don’t succumb to RAS syndrome (redundant acronym syndrome syndrome). Let me go to the ATM machine and give you my PIN number.
4. Working with Words, Numbers, and Dates, As you read in the last chapter, you can use data to make decisions in a named data that stores an array, then store a number in the variable, you've One set of parentheses (labeled 1) wraps around two other parenthetical groups (2 and 3). Fortunately, there's a method for numbers called toFixed(), which lets you It thinks you are trying to type a float like 1.2 and it doesn't like that t there, it's not a number. Interestingly, you can do this without parenthesis or making variable by using 2 decimal points. Like this: 1..toFixed(2). I guess you can also do 1.0.toFixed(2) if you want.
- An number looks like some digits optionally followed by
.and more digits. That's what the parser assumes the
.means here. It's not being misinterpreted; the token syntax for numbers takes precedence over the language grammar.
- @RocketHazmat Nice trick. thanks!
