Question

After spliting a tab delimited file I have my required values in a string variable. Unfortunately the source of this file is out of my control.

Here are three exact example of what the value might hold:

1. ” 5.344″
2. ” -2.345″
3. ” -.977″

Notice the white space, no ‘0’ prefixing the decimal points and the double quotes are in the string. Once I have each one in my field variable this is what I am currently doing:

int_val = BigDecimal(value_as_string.gsub(/-\./,"-0.").gsub(/\"/,'').strip).round(0).to_i

I need each one rounded to the nearest integer (.to_i rounds down). Any better ideas would be much appreciated as I can help but this this stinks!?

Answer 1

def round(s)
    s.to_f.round
end

round("5.344") # 5
round("-2.345") # -2
round("-.977") # -1
