generate 3 digits floating point random number

[gdah]

hai....How I want to generate 3 digits floating point random number??..plz help me...

Thanks..

I want to get the number from 1-5 in 3 digits floating point. For example 3.57. So I have no idea how to get the 3 digits floating point number. Can anyone help me..

Thanks

Floating point numbers have a width expressed by bytes (e.g. double = 8 byte), not in digits. So "digits" in general are a display-thing.
If you choose to "limit" the precision to 3 digits, you can either configure your displays (indicators) to the proper settings (context menu => Display format) or you manually truncate your floating points to 3 digits by converting them either to string and truncate there and revert them to floating points or to convert them in a proper way to integers and back again...

hope this helps,
Norbert

Hi gdah,

use some common math functions to get a randopm number in the range from 1 to 5 (but not including 5, see help for "random number"!)... Then format to a string (if needed) or set properties of numeric indicator...


Hey Mike, your first version looked quite different

Remember that internally to the computer all numbers are expressed as binary. So the number of digits in a decimal expression does not correlate directly with the number of binary bits the computer uses to represent the same number. 0.2, 0.3, and 0.4 for example all have infinitely repeating repeating representations in binary. If you want to limit the size or precision of the numbers in calculations, you should determine the limits in accord with the binary representation of the numbers.
