The new FXRealSpinner widget, contributed by Bill Baxter, is an version of the FXSpinner widget that supports double-precision floating point values. Like the original FXSpinner, this widget provides a "cyclic" mode, where values below the spinner's minimum value "wraps around" to the spinner's maximum and vice versa. The FXRealSpinner also supports a logarithmic mode in which each increment or decrement of the spinner modifies the spinner's value by some power of ten. For example, if the initial value of the FXRealSpinner is 1.0 and the increment value is 1.0, incrementing the spinner will result in the sequence 1.0, 10.0, 100.0 and so on.
