pbf is rounding the Long integer value to nearest value why?

[syamasundararao]

While using VectorGrid Pbf I have faced an issue of rounding of 20 digit number to nearest value
actual value : 2216087363469098752
output value:2216087363469098800

Why I need actual value ..

Because JavaScript stores numbers as 64-bit floating point and can't precisely represent values bigger than Number.MAX_SAFE_INTEGER, which is 9007199254740991. There's a potential solution for this explored in #115.

@syamasundararao In addition to what @mourner said, this library focuses on performance and being unable to accurately represent 64-bit integers is an intentional tradeoff for performance since, until recently, JavaScript did not have native support. This is a reasonable tradeoff because 53-bit integers is sufficient for many use cases.

It's natively supported now, but the performance characteristics have not been deeply explored and progress is being tracked in #115.
