Why Is ToString() Rounding My Double Value?

Question

How do I prevent my double value from being rounded when converting to a string? I have tried both Convert.ToString and ToString() with the same r

Answer 1

Try something like

myDouble.ToString("R")

See also The Round-trip ("R") Format Specifier:

The round-trip ("R") format specifier guarantees that a numeric value that is converted to a string will be parsed back into the same numeric value.
