PRECISION: Command to set the precision unit

syntax: PRECISION=float OR
PRECISION=float,keepvars OR
PRECISION=double OR
PRECISION=double,keepvars OR
PRECISION=longdouble OR
PRECISION=longdouble,keepvars OR
PRECISION=longnum OR
PRECISION=longnum,keepvars

The precision command sets the precision unit. Each precision unit: float, double, long double, long number is actually an individual calculator and each calculator has its own set of 26 letter variables for DECIMAL value storage, excluding string variables which are shared globally. By default all variables of a calculator are transferred over to the new calculator after a precision unit change. Alternatively you can choose not to do this and have each calculator preserve its own set of decimal variables by specifying ",keepvars" after the precision unit name in the precision command. example: precision=longnum,keepvars which will skip tranferring variables from the previous calculator to the long number calculator.


any assignment to variables: $A...$Z will assign to the long number calculator variables as well as the variables in the currently used calculator
