SQRT real-valued function SQRT real-valued function Syntax SQRT (value) Function Return the square root of the parameter. Parameter value Real-valued expression defining the value whose square root is to be computed. Details Returns the square root of the argument if the argument is greater than zero. An error results if the argument is less than zero. The square root of a number is defined to be the number that, when multiplied by itself, yields the original number. Examples SQRT(0.123) ;Returns 0.3507136 SQRT(4) ;Returns 2.0 SQRT(-5.462) ;Returns *Negative square root* SQRT(1.3125E+2) ;Returns 11.45644 NOTE:
TYPE, PROMPT, and similar instructions output the results of the above examples as single-precision values. However, they are actually stored and manipulated as double- precision values. The LIST and LISTR monitor command displays real values to full precision. eV+Language Reference Guide, v2.x, 18319-000 Rev A Page 497
