Hi,I'm trying to determine how to define variables

amtpaid, prevbal, latechg, etc. are database fields that are: decimal 8,2 and may be 0.00 or more:

I'm asking for the correct way to code these variables to reflect their value and been advised:

Code:

$amtpaid = (double)'amtpaid';, 
$amtpaid=$row['amtpaid'];,
$amtpaid = (int)'amtpaid';
$amtpaid = 0; 

Quote:

or told to "use different logic, change language, everything except "just do this".

Obviously I'm resetting the values of the fields to 0 since after update, no matter the amtpaid,
prevbal, latechg, etc. are always 0.00

I want to code them so that php understands their values and I can refer to them. Will someone
answer this question?

A variable is a characteristic that can be measured and that can assume different values. Height, age, income, province or country of birth, grades obtained at school and type of housing are all examples of variables. Variables may be classified into two main categories: categorical and numeric.
