The Display

Status Indicators

Nine indicators that appear along the bottom of the display signify the status of the calculator for certain operations. These status indicators are described elsewhere in this handbook where the relevant operation is discussed.

Number Display Formats

When the calculator is first turned on after coming from the factory or after Continuous Memory has been reset, answers are displayed with two decimal places.

Although you see only two decimal places, all calculations in your hp 12c platinum are performed with full 10-digit numbers.

When only two decimal places are displayed, numbers are rounded to two decimal places: if the third digit is 5 through 9, the second digit is increased by one; if the third digit is 0 through 4, the second digit is not affected. Rounding occurs regardless of how many decimal places are displayed.
