Yes, it says that number of decimal digits for float value is limited to 6 as per IEEE standard.What if I want to write something like this
std::numeric_limits<float>::10--> this gives me error. Is there any otehr alternative for it?“ In order to be irreplaceable, one must always be different” – Coco Chanel

I don't understand what you want to do
std::numeric_limits<float>::digits10is a constant value (is same asFLT_DIG).
It represent the number of decimal digits that are guaranteed to be preserved in text.What should be
std::numeric_limits<float>::10?It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth. (Sherlock Holmes)

std::numeric_limits<float>::10?in the above case, the number of decimal digits is 6 as per IEEE standard. Suppose I want the decimal digits to be 10 , is there any notation apart from qRound() which achieves it?

Again, this is not a parameter, this is a constant: only a 6 digits decimal constant can be stored "loose-less" in in float. 999999 can be store in a float, above this value there will be a little error because of the storing format.
qRound()will give you the nearest integer value for a float/double valueIt is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth. (Sherlock Holmes)

Thanks for your explanation. -

No this is false. It will be rounded at the nearest integer.

Thanks for your clarification.
