The package modifies the behaviour of characters in maths mode so that:
‘.’ is used as a one-thousand separator (as is common in Germany)
‘,’ is used as a decimal separator (as is common in Germany)
‘--’ is represented with spacing as appropriate to such constructs as ‘1.000,--’.

These conversions may be switched on and off.
