Calculator — Windows 98 Simulator

The Windows 98 Calculator opens in Standard view, but one click on View > Scientific turns it into the engineer’s calculator of the decade, with hex, binary and the Statistics Box. It was a staple of every school and office desktop.

Calculator from Windows 98 in both of its views. Standard does everyday arithmetic with memory (MC, MR, MS, M+), percent and square root.

View > Scientific adds operator precedence and parentheses, Hex / Dec / Oct / Bin with Dword, Word and Byte, Inv and Hyp functions, degrees, radians and grads, and the Statistics Box.
