Hello Daniweb Forum People, I have this problem of getting the decimal of a number? How can I get it and copy to a variable?
ex.... 1234.59
I used a for loop in order to get the index value of 59, my problem was with the value? how can I transfer this index number to a variable?

Not a clue what you are talking about.

Im having a problem of getting the values of this string for example
1234.56, I want to extract the 56 in order to have that value. I used a for loop? I am right or their other way how to that?
How can i passed on the value of that extracted to an int one. Thanks

strchr() can find where the period is, the rest is the decimal part.
strtol() can convert the decimal part into a long int.
strtol() can convert the decimal part into a long int.

This is my code snippet any help in order to get the decimal for example of this no. 1234.56? thanks.
strchr() returns a pointer to the first occurrence of the character you want, not to an int.
A call to strtol() will convert string number value representation to long int.

If you just want to extract the index (part after the decimal pointer) you can use this method also (in case your index part is in integer bounds)
If you have scanned it as a floating point number:
1>Convert it into a STRING.
2>Then use standard function strtok() with the delimiter as "." and get the second token.
3>This is your index but in string format.
4>Convert it into an integer number.
If you have taken the input as string itself and want the index to be in string format only then disregard step 1 and 4.

That's not Aia's code, and it seems to be incorrect. Here's a working example. It lacks proper error checking for strtol, though. See the link in Aia's post above for the scoop on strtol.
