How to check for a Numeric Value?

Using shell,

I have a variable, how can I check that variable for a numeric value such as "41.0"? My program needs to do one things if the numeric value is found, and another if something else such as a string of letter is found. is there a specific character that denotes a numeral? The numerals will always be a decimal number rounded to the tenth as above. Some numerals could be five digits though, including the decimal, such as "376.0". Can anyone help me?
