Floats are used to represent floating-point numbers such as decimal points anywhere within the number.
Float is a 64-bit data type used to represent floating-point numbers. Floating-point numbers can either include a decimal point anywhere within the number or the decimal point entirely. An exponent can optionally be used following the number to increase the number's range, for example:
1.777 e-20
Binary floating-point numbers differ from Integer in the way the values are represented internally during processing by Sybase CEP Engine. Binary floating-point numbers are stored using binary precision (the digits 0 and 1). Such a storage scheme cannot represent all values exactly. Converting a value from decimal to binary may result in an error, but the error is often eliminated when the number is converted back to decimal precision.
