| value = a number, or a string which represents a number |

This is the same as Blitz's automatic type conversion.
So the two commands... y# = value y# = Float( value ) ... do exactly the same thing. If Float is applied to a string it converts as much as possible: Float( "10" ) ...... result is 10.0 Float( "3junk" ) .. result is 3.0 Float( "junk3" ) .. result is 0.0 In the latter two examples Float() stops converting when it sees "j". The typical use is to force floating point arithmetic: y# = 12 / 5 .............. result is 2.0 because 12 / 5 = 2 ( integer division ) y# = float( 12 ) / 5 .... result is 2.4 |
