Real variables are represented by any variable with the suffix #, e.g. B# or MYVAR#. They are stored as 64-bit double-precision IEEE 754 floating point values.

Examples

PI# = 3.14159
radius# = 5.5
area# = PI# * radius# * radius#
PRINT "Area = "; area#

REM Mixing integers and reals
A = 10
B# = 3
PRINT A / B#

Produces 3.33333... since the operation is promoted to real.

Notes

Range and precision follow IEEE 754 double format.
Supports fractional values, scientific notation, and very large or very small numbers.
Operations involving both integer and real variables are promoted to real.
Rounding can be applied with ROUND.
