The DTWAIN_RangeGetPosFloat is a specialized version of DTWAIN_RangeGetPos where Value is the DTWAIN_FLOAT data instead of a void pointer.

This function can only be used by ranges that were created using DTWAIN_RANGEFLOAT.

If the value is not found in the range, lpPosition will return the "closest" index to the number.

TWAIN State Transitions

None.
