c# - Retain decimal places in toString -

is there way create resulting string 'double.tostring()' contain exact value of double?

for example

double d = 123.0 -> tostring() "123"

i've found little bit of solution in using custom format .tostring("#.0") if want add together more decimal places i'm started

double d = 123.00 -> tostring("#.0") 123.0 double d = 123.0 -> tostring("#.00") 123.00

the reason i'm trying because i've got custom text boxes must utilize different value 1 thats displayed , when trying come in own value text box textbox ignoring text when seek come in 0 in decimal places. hence need tostring value equal exact value of double number can entered properly.

thank you

it does contain exact value of double - double doesn't store difference between 123, , 123.0 , 123.00.

decimal stores difference, - , far more appropriate if care exact decimal digits anyway.

on other hand, sounds actually you're doing comparing in wrong place:

don't compare string values - parse value (to either decimal or double) , compare parsed values.

this prevent problems leading zeroes, "0123" , "123" represent same value, different strings.
