float (expression)
Description
Function; converts an expression to a floating-point number. The number of digits that follow
the decimal point (for display purposes only, calculations are not affected) is set using the
floatPrecision property.

put (1).float
-- 1.0
Math operations can be performed using float; if any of the terms is a float value, the entire
operation is performed with
float:
"the floatPrecision = 1
put 2 + 2
-- 4
put (2).float + 2
-- 4.0
the floatPrecision = 4
put 22/7
-- 3
put (22).float / 7
-- 3.1429"
