fixed.extractNumericType
Description
Examples
Extract the numeric type from an input numeric value.
T = fixed.extractNumericType(pi)
T = DataTypeMode: Double
T = fixed.extractNumericType(int8(0))
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 8 FractionLength: 0
T = fixed.extractNumericType(fi(pi,1,24,12))
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 24 FractionLength: 12
T = fixed.extractNumericType(half(pi))
T = DataTypeMode: Half
Extract the numeric type from a numeric type specification object.
T = fixed.extractNumericType(numerictype(1,32,16))
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 32 FractionLength: 16
T = fixed.extractNumericType(fixdt(0,18,0))
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Unsigned WordLength: 18 FractionLength: 0
Extract the numeric type from a data type name string.
T = fixed.extractNumericType('int8')
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 8 FractionLength: 0
T = fixed.extractNumericType('sfix16_En3')
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 16 FractionLength: 3
Extract the numeric type from a constructor string.
T = fixed.extractNumericType('numerictype(1,33,55)')
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 33 FractionLength: 55
T = fixed.extractNumericType('fixdt(0,77,22)')
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Unsigned WordLength: 77 FractionLength: 22
