No. The compiler will optimize the cast away assuming it can. It's probably
generating something like this:

private static void Blah()
.locals (float V_0, float V_1)
L_0000: ldc.r4 1.23
L_0001: stloc.0
L_0002: ldc.r4 4.56
L_0003: stloc.1

from this:

static void Blah()
{
    float f1 = 1.23F;
    float f2 = (float) 4.56;
}
