Get a more precise number of this formula with W|A?

[mzprzybylski (Michael Przybylski)]

Why I can’t get more precise number than to two digits after the dot?

My formula:

 =N[(1/( sqrt(((universal gravitational constant)*(Planck's constant))/(speed of light)^5)))/(golden number)^201,5]]


=7.29 per second

what is the precision of the inputs?

I don’t fully understand your question, but this can probably this wil help !

1. Display the first 10 digits of a numeric approximation to [Pi]:

NumberForm[N[Pi], 10] (* 3.141592654 *)

2.Display a number with 3 precise digits and 4 digits to the right of the decimal:

DecimalForm or NumberForm[1.23456, {3, 4}] (* 1.2300 *)

Other option:

N[1/3. // Rationalize, 3] (* 0.333 ) or N[23100/34, 3] (* 67.6 *)

Thank You Jos for additional information but for my formula, this has no effect.
Please check if you can get a more precise result.

[ =N[(1/( sqrt(((universal gravitational constant)*(Planck’s constant))/(speed of light)^5)))/(golden number)^201,5]]]2

Hallo, Frank,
data input for this eq are as follows:

=(universal gravitational constant)

=(Planck’s constant)

=(speed of light)

=(

)

only for (GoledenRatio) I can change precision in output =N[(GoldenRatio),10]
