RDX,

This operation switches between the "." and the "," character to represent the radix point in numerical output. By default, this setting is derived from the locale conventions set on the device but it can be changed to deviate from those conventions using this operation.

When set, the "," character separates the integer and fractional part of a number while the "." character is used to separate values (for example between the real and imaginary part of a complex number). When unset, the "." character separates the integer and fractional part of a number while the "," character is used to separate values.
