real-valued function
function whose range is a subset of the real numbers
function of bounded mean oscillation
real-valued function whose mean oscillation is bounded
real part
projection of a complex number onto the real number line
objective function
in mathematical optimization, a function (to be optimized) representing the desirability (or undesirability) of each outcome
absolute value
function which measures the "size" of elements in a field or integral domain
Entanglement measure
Function that quantifies the amount of entanglement present in a quantum state
imaginary part
function from the complex numbers to the reals that maps a+bi to b, where a and b are real
radial basis function
real-valued function whose value depends only on the distance between the input and some fixed point, which forms a basis for some function space

nonnegative-real-valued function on a ring satisfying the triangle inequality and submultiplicativity
integer-valued function
function that ranges over the integers
power curve
in statistics
