6.3.5 INT64, UINT64, or QWORD
Source Conversion
BOOL The source value of zero or one is assigned to the destination.
INT8, UINT8, CHAR,
BYTE, INT16,
UINT16, WORD,
INT32, UINT32, or
DWORD
The source data value is assigned to the destination (sign extend where
appropriate).
INT64, UINT64, or
QWORD
The source value is copied directly to the destination possibly resulting in a
signed/unsigned value change.
FLOAT32 or
FLOAT64
The source value is rounded to the nearest INT64 value and the above
INT64 to 64 bit INT conversion rule applied. If the rounded source value will
not fit in an INT64 a conversion error will result.
STRING The string is converted to INT64 and moved according to the above INT64
to 64 bit INT conversion rule. If the string could not be converted to INT64
(invalid chars, overflow, and so on) a conversion error will result.
6.3.6 Float32
Source Conversion
BOOL The source value of zero or one is assigned to the destination.
INT8, UINT8, CHAR,
BYTE, INT16,
UINT16, WORD,
INT32, UINT32,
DWORD, INT64,
UINT64, or QWORD
The source data value is assigned to the destination possibly resulting in a
loss of precision.
FLOAT32 Direct Assignment.
FLOAT64 If source val < -3.4e38 or source val > 3.4e38 a conversion overflow error
will result. Otherwise, the source value will be assigned to the destination
with a loss of precision.
STRING The string (with possible exponent) is converted to FLOAT32. If the string
could not be converted to a FLOAT32 (invalid chars, overflow, and so on) a
conversion error will result.
6.3.7 Float64
Source Conversion
BOOL The source value of zero or one is assigned to the destination.
INT8, UINT8, CHAR,
BYTE, INT16,
UINT16, WORD,
INT32, UINT32,
DWORD, INT64,
UINT64, or QWORD
The source data value is assigned to the destination possibly resulting in a
loss of precision.
FLOAT32 The source data value is assigned to the destination.
FLOAT64 Direct assignment.
STRING The string (with possible exponent) is converted to FLOAT64. If the string
could not be converted to a FLOAT64 (invalid chars, overflow, and so on) a
conversion error will result.
