* Exponential operations are done first in the Qbasic order of operations.
* The square root of a number can be returned by the [[SQR]] function or by using an exponent of (1 [[/]] 2). Brackets required.
* Values returned may be expressed using exponential or [[Scientific notation]] using '''E''' for SINGLE or '''D''' for DOUBLE precision.
* WARNING: Exponential returns may exceed numerical type limitations and create an [[ERROR Codes|overflow error]]!
''Example:'' Getting the cube root of a number.
{{CodeStart}}
{{Cl|INPUT}} "Enter a number to calculate it's cube root: ", num$
number! = {{Cl|VAL}}(num$) 'gets single number value
cuberoot# = number! {{Cl|^}} (1 {{Cl|/}} 3)
PRINT cuberoot# 'double type variable for accuracy
{{CodeEnd}}
''Details:'' The value returned will most likely be a [[SINGLE]] or [[DOUBLE]] value. Make sure that the return variable type matches the likely program operations!
