HP 40G manual 175@ updates ANS from 50 to 75 to, 50175@ @25 175@175@

Example	See how >6+,)7@ANS retrieves and reuses the last result (50),
	and >(17(5@ updates ANS (from 50 to 75 to 100).
	50>(17(5@ >￿@￿25
	>(17(5@>(17(5@

You can use the last result as the first expression in the edit line without pressing >6+,)7@ANS. Pressing >￿@, >￿@, >;@, or >j@, (or other operators that require a preceding argument) automatically enters ANS before the operator.

You can reuse any other expression or value in the HOME display by highlighting the expression (using the arrow keys), then pressing &23<a. See “Using previous results” on page 1- 21 for more details.

The variable ANS is different from the numbers in HOME’s display history. A value in ANS is stored internally with the full precision of the calculated result, whereas the displayed numbers match the display mode.

H I N T When you retrieve a number from ANS, you obtain the result to its full precision. When you retrieve a number from the HOME’s display history, you obtain exactly what was displayed.

Pressing >(17(5@ evaluates (or re-evaluates) the last input, whereas pressing >6+,)7@ANS copies the last result (as ANS) into the edit line.
