    • A method, device and system for representing numbers in a computer including storing a floating-point number M in a computer memory; representing the floating-point number M as an interval with lower and upper bounds A and B when it is accessed by using at least two floating-point numbers in the memory; and then representing M as an interval with lower and upper bounds A and B when it is used in a calculation by using at least three floating-point numbers in the memory. Calculations are performed using the interval and when the data is written back to the memory it may be stored as an interval if the size of the interval is significant, i.e. larger than a first threshold value. A warning regarding the suspect accuracy of any data stored as an interval may be issued if the interval is too large, i.e. larger than a second threshold value.
    • 一种用于在计算机中表示数字的方法,装置和系统,包括将浮点数M存储在计算机存储器中; 当通过使用存储器中的至少两个浮点数来访问时,将浮点数M表示为具有下限和上限A和B的间隔; 然后当在计算中使用存储器中的至少三个浮点数时,将M表示为具有下限和上限A和B的间隔。 使用间隔执行计算,并且当数据被写回存储器时,如果间隔的大小是显着的,即大于第一阈值,则可将其存储为间隔。 如果间隔太大,即大于第二阈值,则可以发出关于作为间隔存储的任何数据的可疑精度的警告。
