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.
