square rooting in VB

[doughnut]

Hey,
can anyone tell me how to square root stuff inside a text box,cant seem to find out.

[whitetiger0990]

it's basicly this

Code:

Text1.Text = Sqr(Text1.Text)

[Mech1031]

not quite. i tried that and it didn't work for me. use this formula.

Code:

Num = val(text1.text)
Answer = Num^.5

easy...

it's basicly this

Code:

Text1.Text = Sqr(Text1.Text)

you just gotta do this:

Code:

Text1.Text = Str(SQR(Val(Text1.Text)))

[whitetiger0990]

it worked on mine without turning it into a string and back

...use this formula.

Code:

Num = val(text1.text)
Answer = Num^.5

Mech, that's brilliant! I never thought you could raise a number to .5 to get the square root. I wrote a little program to test it.

Who said you can't teach an old dog new tricks.
Thanks!

Well, that's just math. The Nth root of a number is that number powered to the 1/Nth power.

-(n^-1) is the negative reciprocal of a number.
Whatever. :roll:

VB has a "VARIANT" default. :*)

To be exactly....

nSQR is the n-th root of a number.

Code:

nSQR(x ^ p) = x ^ (p/n)
