BESSELI

Calculates the modified Bessel function of the first kind In(x).

Syntax

BESSELI(X; N)

X is the value on which the function will be calculated.

N is a positive integer (N >= 0) representing the order of the Bessel function In(x)

Example

Example

=BESSELJ(3.45, 4), returns 0.196772639864984

=BESSELJ(3.45, 4.333), returns 0.196772639864984, same as above because the fractional part of N is ignored.

=BESSELJ(-1, 3), returns -0.019563353982668

BESSELK

Calculates the modified Bessel function of the second kind Kn(x).

Syntax

BESSELK(X; N)

X is the strictly positive value (X > 0) on which the function will be calculated.

Example

=BESSELK(3.45, 4), returns 0.144803466373734

=BESSELK(3.45, 4.333), returns 0.144803466373734, same as above because the fractional part of N is ignored.

=BESSELK(0, 3), returns Err:502 – invalid argument (X=0)

BESSELY

Calculates the Bessel function of the second kind Yn(x).

Syntax

BESSELY(X; N)

X is the strictly positive value (X > 0) on which the function will be calculated.

N is a positive integer (N >= 0) representing the order of the Bessel function Yn(x)

Example

=BESSELY(3.45, 4), returns -0.679848116844476

=BESSELY(3.45, 4.333), returns -0.679848116844476, same as above because the fractional part of N is ignored.

=BESSELY(0, 3), returns Err:502 – invalid argument (X=0)

BIN2DEC

The result is the decimal number for the binary number entered.

Syntax

BIN2DEC(Number)

Number is a binary number. The number can have a maximum of 10 places (bits). The most significant bit is the sign bit. Negative numbers are entered as two's complement.

Example

=BIN2DEC(1100100) returns 100.

BIN2HEX

The result is the hexadecimal number for the binary number entered.

Syntax

BIN2HEX(Number; Places)

Number is a binary number. The number can have a maximum of 10 places (bits). The most significant bit is the sign bit. Negative numbers are entered as two's complement.

Places means the number of places to be output.

Example

=BIN2HEX(1100100;6) returns 000064.

BIN2OCT

The result is the octal number for the binary number entered.

Syntax

BIN2OCT(Number; Places)

Number is a binary number. The number can have a maximum of 10 places (bits). The most significant bit is the sign bit. Negative numbers are entered as two's complement.

Places means the number of places to be output.

Example

=BIN2OCT(1100100;4) returns 0144.

DEC2BIN

The result is the binary number for the decimal number entered between -512 and 511.

Syntax

DEC2BIN(Number; Places)

Number is a decimal number. If Number is negative, the function returns a binary number with 10 characters. The most significant bit is the sign bit, the other 9 bits return the value.

Places means the number of places to be output.

Places means the number of places to be output.

Example

=DEC2HEX(100;4) returns 0064.

DEC2OCT

The result is the octal number for the decimal number entered.

Syntax

DEC2OCT(Number; Places)

Number is a decimal number. If Number is negative, the function returns an octal number with 10 characters (30 bits). The most significant bit is the sign bit, the other 29 bits return the value.

Places means the number of places to be output.

Example

=DEC2OCT(100;4) returns 0144.

DELTA

The result is TRUE (1) if both numbers, which are delivered as an argument, are equal, otherwise it is FALSE (0).

Syntax

DELTA(Number1; Number2)

Example

=DELTA(1;2) returns 0.

ERF

Returns values of the Gaussian error integral.

Syntax

ERF(LowerLimit; UpperLimit)

LowerLimit is the lower limit of the integral.

UpperLimit is optional. It is the upper limit of the integral. If this value is missing, the calculation takes place between 0 and the lower limit.
