MS SQL Serever 2008 R2 value fro REAL type

For fields such as real value displayed incorrectly. For example, for the value 0.38, displayed 0.379999995231628!

CREATE TABLE "Meters" (
    "MeterId" INT NOT NULL,
...
    "VoltageLevel" REAL(24) NULL DEFAULT NULL,
...
    PRIMARY KEY ("MeterId")
)
;

REAL (together with FLOAT) belongs to the Approximate Numerics data types so it's possible that the value shown by HeidiSQL is closer to the actual one than the display value shown by Navicat Premium.

I've been playing with other clients and I get 0.38 with Microsoft SQL tools (sqlcmd and Management Studio) and 0.37999999523163 when connecting from PHP.

BTW, I think that column definition should be FLOAT(24) or REAL.
