    Fractions with the same denominator have circles of the same size. In the special case when the circle method is applied to find the coefficients of a modular form of negative weight, Hans Rademacher found a modification of the contour that makes the series arising from the circle method converge to the exact result.

    It was later reduced to 3.5, 3.3, and 2.5 volts to lower power consumption. For example, the Pentium P5 core voltage decreased from 5V in 1993, to 2.5V in 1997. With lower voltage comes lower overall power consumption, making a system less expensive to run on any existing battery technology and able to function for longer.
