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} .

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)
