Block SymbolLicensing group: STANDARD

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

$\mathtt{\text{y}}=\sqrt{\mathtt{\text{u}}}.$

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

Input

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