natural logarithm
logarithm to the base of the mathematical constant e
inverse function
function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa. i.e., f(x) = y if and only if g(y) = x
square
result of multiplying a number, or other expression, by itself
multiplicative inverse
of a number x, 1 divided by x
logical negation
In logic, negation, also called the logical not or logical complement, is an operation that takes a proposition P to another proposition "not P", written \neg P, \mathord{\sim} P, P^\prime or \overline{P}. It is interpreted intuitively as being true when P is false, and false when P is true. For example, if P is "The dog runs", then "not P" is "The dog does not run". An operand of a negation is called a negand or negatum.
cube root
number which produces a given number when cubed
sign function
mathematical function that extracts the sign of a real number or complex number
unary operation
mathematical operation with only one operand
counter
device which stores the number of times a particular event or process has occurred
cube
product of a number being raised to the third power
floor and ceiling functions
functions of a real returning respectively the largest smaller and the smallest larger integer
magnitude
mathematical concept related to comparison and ordering
ones' complement
value obtained by inverting all the bits in the binary representation of the number
type conversion
changing an expression from one data type to another
fractional part
excess beyond the integer part of a number
increment and decrement operators
unary operators that add or subtract one from their operand, respectively
fourth power
result of multiplying four instances of a natural number together
fifth power
result of multiplying five instances of a natural number together
barrel shifter
digital circuit that implements a bit-shift operation
sixth power
result of multiplying six instances of a number
seventh power
Result of multiplying seven instances of a number
eighth power
result of multiplying eight instances of a number together
sizeof
'''''' is a unary operator in the C and C++ programming languages that evaluates to the storage size of an expression or a data type, measured in units sized as char. Consequently, the expression sizeof(char) evaluates to 1. The number of bits of type char is specified by the preprocessor macro CHAR_BIT, defined in the standard include file limits.h|. On most modern computing platforms this is eight bits. The result of sizeof is an unsigned integer that is usually typed as .
unary function
function that takes one argument. In computer science, a unary operator is a subset of unary function
