sub function modf(dim val as real, dim byref iptr as real) as real

The function returns the signed fractional component of 

val

, placing its whole

number component into the variable pointed to by 

iptr

.

sub function pow(dim x as real, dim y as real) as real

The function returns the value of 

x

raised to the power y (i.e. 

xy

). If 

x

is nega-

tive, the function will automatically cast 

y

into 

longint

.

sub function sin(dim arg as real) as real

Description The function returns the sine of arg in radians. The return value is from -1 to 1.

sub function sinh(dim x as real) as real

The function returns the hyperbolic sine of 

x

, defined mathematically as 

(ex-e-x)/2

.

If the value of 

x

is too large (if overflow occurs), the function fails.

sub function sqrt(dim x as real) as real

Description The function returns the non negative square root of 

x

.

sub function tan(dim x as real) as real

The function returns the tangent of 

x

in radians. The return value spans the

allowed range of floating point in mikroBasic PRO for AVR.

sub function tanh(dim x as real) as real)

The function returns the hyperbolic tangent of 

x,

defined mathematically as

sinh(x)/cosh(x).
