Built-In Functions

Function

Return Value

ABS(x)

Absolute value of x.

CEIL(x)

Returns the smallest integer greater than or equal to x (rounds x toward positive infinity)

DB(x)

(sign of x)*20*log₁₀(abs(x)) [x expressed in deciBels, with the sign of x]

DB_NONINVERTING(x)

20*log₁₀(abs(x)) [x expressed in deciBels]

EXP(x)

e^x

FLOOR(x)

Returns the largest integer less than or equal to x (rounds x toward negative infinity)

FMOD(x,y)

x -i *y for some integer i, such that if y is non-zero the result has the same sign as x and magnitude less than y.

IMAG_PART(x)

Imaginary part of complex value x. IMAG(x) is an alias.

INT(x)

Integer portion of x

LOG(x)

log_e(x), error if x≤0

LOG10(x)

log₁₀(x), error if x≤0

MAX(x,y)

x if x > y, y if y ≥ x

MIN(x,y)

x if x < y, y if y ≤ x

NINT(x)

Rounds x up or down to nearest integer. A fractional part of .5 is rounded UP to the nearest integer. NINT(-1.5) is -1 and NINT(1.5) is 2.

PHASE_D(x)

Phase of complex value x in degrees

PHASE_R(x)

Phase of complex value x in radians

POW(x,y)

x^y

PWR(x,y)

SGN(x)|x|^y

REAL_PART(x)

Real part of complex value x. REAL(x) is an alias.

SIGN(x,y)

abs(x) if y ≥ 0

-abs(x) if y < 0

SGN(x)

-1 if x < 0, 0 if x = 0, 1 if x > 0

Positive square root of x

Function

Return Value

ACOS(x)

Inverse cosine of x in radians

ASIN(x)

Inverse sine of x in radians

ATAN(x)

Inverse tangent of x in radians

ATAN2(x,y)

For any real arguments (x, y) not both zero, the angle in radians between the positive X-axis and the point (x, y). The angle is positive for y > 0 and negative for y < 0.

COS(x)

Cosine of x in radians

COSH(x)

Hyperbolic cosine of x in radians

HYPOT(x,y)

SQRT(x**2 + y**2)

SIN(x)

Sine of x in radians

Hyperbolic sine of x in radians

TAN(x)

Tangent of x in radians

TANH(x)

Hyperbolic tangent of x in radians
