The nsub is a built-in function that returns the difference all of its arguments starting from the leftmost arguments and returns the result as a Number quantity. The operands are not checked and are not coerced.


The nsub built-in function is a simple, but very fast numeric subtraction function that assumes all of its arguments are type Number. Use the nsub function for highly optimized numeric subtraction. For a slower, but more general subtraction, that performs type conversion, use the subtraction operator, -, (minus sign).




(nsub num1 num2, ... )

Arguments Name Type Description
Argument:num1Number The first number to be subtracted.
Argument:num2Number An arbitrary number of Number operands.


The difference all of its arguments starting from the leftmost arguments expressed as a Number.
