Memory Handling <memory.h>
The header <memory.h> declares several functions useful for manipulating character
arrays and other objects treated as character arrays. The following functions are declared
by this header file:
pow() function Returns the value of a number raised to the power of an exponent.
signgam external
integer
Contains the sign of the value returned by the gamma function.
sin() function Computes a sine value.
SING macro Expands to an integral constant.
sinh() function Computes the hyperbolic sine of an angle.
sqrt() function Computes the square root of an input value.
tan() function Computes a tangent value.
tanh() function Computes the hyperbolic tangent value of an angle.
TLOSS
e
macro An integral constant returned through errno when an arithmetic
error has occurred.
y0() function Return Bessel functions of
x
of the second kind of order zero.
y1() function Return Bessel functions of
x
of the second kind of order one.
yn() function Return Bessel functions of
x
of the second kind of order
i
