Major Calculator app bug in 15.7

[IvyKing]

The app has a weird error with the way functions such cos, 10^x, etc when the argument is negative. For example, 10 raised to the power of -1 should return 0.10, but the function returns -10.0. Similarly, cos of -60 degrees should return 0.5, but the function returns -0.5.

The 14.8 app does not have this error.

When I enter 10^-1, I get the correct answer of 0.10

When I enter Cos(-60) in degree mode, I get the correct answer of 0.5

I am using macOS Sequoia 15.7.

I left out that this happens in RPN mode, but not in normal mode. Seems like the RPN mode has a funky way of handling the sign of the argument.

I appreciate the reply.
