Does the double (or float) potentially do any Mantissa rounding?

isnt it more like truncation?

Hi,

I’m familiar with other uses of float where a float number (after a computation) that yields a 12345678.9999999999999 results rounds up to 12345679.

The reason for the question: I’ve got a CBock with a uint64 output. The output value can use about 52 the bits of the uint64. If I use the out value in a Bsource equation, do I lose any of the bits in Mantissa rounding?
