TRUNCATE a FLOAT [ 3,45 ] -> [ 3 ]

TRUNCATE a FLOAT [ 3,45 ] -> [ 3 ]

[helder da silva]

Anyone remembers how to truncate the first part of a float number :

FROM ( float ) :  3,45

TO ( integer )  :  3

I've got a blank on this one !

Thanks.

given the declarations

X : Float;
Y : Integer;

you can write

Y := Integer (Float'Floor (X));

This must be a FAQ; we just had a thread on floating-point attributes.

Check out your ARM Annex K for the attribute 'Truncation. While you're
there, look at 'Floor and 'Ceiling, too.

Integer (Float'Trucation (3.45) ) = 3
