DFD Convert I16 to FXP (scalar)

	quantization settings specifies the settings of the quantizer. source specifies the quantizer source. 0 Coefficients a/k (default) 1 Input 2 Output 3 Multiplicand 4 Product 5 Sum 6 Delay 7 Coefficients b/v wl specifies the word length, in number of bits, that the quantizer uses to represent a fixed-point number. The default is 16. iwl specifies the integer word length, in number of bits, within wl that the quantizer uses to represent the integer part of a fixed-point number. The default is 1. iwl can be any integer value. overflow mode specifies how this VI handles overflows and underflows in the quantizer. 0 Saturation 1 Wrap (default) rounding mode specifies the rounding mode this VI uses in the quantizer. 0 Nearest 1 Truncation (default) signed? specifies if the fixed-point number is a signed number. This VI supports signed numbers only. If you remove the checkmark from the signed? checkbox, the result you obtain might not be correct.
	I16 specifies a 16-bit signed integer.
	FXP value returns a fixed-point number.
