Number.toFixed() not rounding per specification

Sun 2019.08.11

toFixed() Does not round as does at the MDN site

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toFixed
"toFixed() returns a string representation of numObj that does not use exponential notation and has exactly digits digits after the decimal place. The number is rounded if necessary, and the fractional part is padded with zeros if necessary so that it has the specified length."

>var kwh = 1234.505;
>kwh.toFixed(2)
"1234.50"

This rounds correctly in the try it window at Mozilla link above


From MDN Correct string representation and rounding

>(1234.505).toFixed(2)
="1234.51"

>process.env

EDIT:
@AkosLukacs documented two other samples in #4 #8

Had a thought, could this anomaly be related to the recent discovery of floating point number of digits to right of zero not matching different browsers and node.js output? hmmmm. . . .
