Subject: Make sure folded float constants appear as correct type
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=29fb23fb9c6eb32b1157a09cf79754a630702f9e

Make sure folded float constants appear as correct type

If the value has no fractional part, the default conversion will not
add a decimal point.
