bor@itsrm2% float var1
bor@itsrm2% var1=$((3.0/2))
bor@itsrm2% print $var1

typeset description:
-E
Use an internal double-precision floating point
representation. On output the variable will be converted to
scientific notation. If N is nonzero it defines the number
of significant figures to display; the default is ten.
-F
Use an internal double-precision floating point
representation. On output the variable will be converted to
fixed-point decimal notation. If N is nonzero it defines the
number of digits to display after the decimal point; the
default is ten.
