RTOS – Real number to string conversion

Block SymbolLicensing group: STANDARD

Function Description
The RTOS converts a real number in u into a string value in su. Precision and format are specified by the prec and mode parameters. Possible values of the mode parameter are:

1: Best fit – fixed point, but for extremely small or big numbers exponential format; parameter prec is total maximum number of characters in output (mantisa for exponential format)
2: Normal – fixed point format; parameter prec is number of places after the decimal point
3: Exponential – scientific format; parameter prec is number of places after the decimal point

This block propagates the signal quality. More information can be found in the 1.4 section.

Input

u	Analog input of the block	Double (F64)

Parameter

prec	Precision (number of digits) $↓$ 0 $↑$ 20	Long (I32)
mode	Output string format $⊙$ 1	Long (I32)
	1 .... Best fit 2 .... Normal 3 .... Exponential

Output

sy	String output value	String
