"In response to a client's need for very high precision, we had to fit a new extended-precision class into our product, which is comprised of hundreds of modules, in a very short time. We were able to incorporate Base One's Number class into our product in just over a week - that's how simple it is to integrate. Technical support throughout the process was superb. Thanks to an extremely well-designed class, and the top-notch help we got from the Base One staff, we were able to provide the new capability with virtually no impact on overall performance ... Our experience was positive in every respect -- high performance, stable code, supported by extremely capable and highly available staff."

"We were astounded to discover how many of our reports showed discrepancies before and after trying out the Base/1 Number Class. We checked the arithmetic and confirmed that Base One's calculations were right."
