SQRT – Square root

Block SymbolLicensing group: STANDARD

Function Description
The SQRT block computes the square root of the input u. The output is then

y = \sqrt u . <math xmlns="http://www.w3.org/1998/Math/MathML" display="block"><mrow> <mstyle class="text"><mtext class="texttt" mathvariant="monospace">y</mtext></mstyle> <mo class="MathClass-rel">=</mo> <msqrt><mrow><mstyle class="text"><mtext class="texttt" mathvariant="monospace">u</mtext></mstyle></mrow></msqrt><mo class="MathClass-punc">.</mo> </mrow></math>

In case $u < 0$ , the error indicator is activated ( $E = on$ ) and the output y is set to the substitute value $y = yerr$ .

Input

u	Analog input of the block	Double (F64)

Outputs

y	Square root of the input signal	Double (F64)
E	Error flag	Bool
	off .. No error on ... Square root of negative number

Parameter

yerr	Substitute value for an error case $⊙$ 1.0	Double (F64)
