ArtistA beautiful purple-haired woman wearing a long purple velvet ankle-length dress with flouncy sleeves and purple suede high heels. She is using an abacus.
::SHE+ILA:: has the standard range of arithmetic and logical operators (ALUOPS) -- see "Boolean and comparisons" for the logical ones. Here is a sample of the arithmetic ones :
x + y Add -- gives the algebraic sum
x - y Subtract -- gives the algebraic difference
x ~ y Difference -- gives the absolute positive difference
x * y Multiply -- gives the product
x $/ y Divide -- gives the quotient. Note the dollar sign since "/" on its own means "Reduce"
x | y Remainder -- gives the remainder of the division
x $X y (or x $> y) Maximum -- gives the maximum (greatest) of x and y
x $N y (or x $< y) Minimum -- gives the minimum (least) of x and y
x ^ y Exponentiation -- gives x to the power of y
*x Signum -- gives -1 if x<0, 0 if x==0, +1 if x>0
|x Absolute -- gives the pythagorean absolute value of x. X may be a quaternion.
$N x (or $< x) Floor -- gives the integer part of x, truncated down
$X x (or $> x) Ceiling -- gives the next integer above x (truncated up)
$G x Natural log of x
$R x Real -- gives the real part of x
$Q x Quaternion -- gives the quaternion (vector imaginary) part of x
$i x Gives the "i" component of x
$j x Gives the "j" component of x
$k x gives the "k" component of x.
