Scientic notation

[LindaRichard]

Hi,

I am trying to display the number 0.00000009 using
scientific notation. I set the .format property of
a text box at ^ and it displays 9.0000E-8. I would
like to control the precision of the number displayed.
For example I want to display 9.0E-8. I tried setting
.format to 9.9^ and #.#^ but this had no effect.

Any suggestions are appreciated.

Thanks
Linda

Short of parsing out the unwanted zeros, I don't think there is another option in VFP.

While STR() will give Scientific Notation for large numbers, it doesn't work for small ones.

? STR(1234567890123,7) &&  1.E+12
? STR(1234567890123,8) &&  1.2E+12
? STR(1234567890123,9) &&  1.23E+12

Linda,

I don't think you can do that. By definition, scientific notation displays whatever precision the number is expressed in. The only way to get rid of those extra zeroes would be to parse them out, as Rick suggested.

Thank you both for taking the time
to answer my question.

I will do as you suggested and parse them out.

Thanks again

Linda
