Returns the modified Bessel function In(x). | BESSELI(X, N) | |

Calculates the Bessel function Jn(x). | BESSELJ(X, N) X is the value at which to evaluate the function. N is the order of the Bessel function. If n is not an integer, it is truncated. | |

Returns the modified Bessel function Kn(x). | BESSELK(X, N) | |

Returns the Bessel function Yn(x). | BESSELY(X, N) | |

Converts a binary number to decimal. | BIN2DEC(number) | |

Converts a binary number to hexadecimal. | BIN2HEX(number, [places]) Number is the binary number to be converted. Places is the number of characters to use. If places is omitted, the minimum number of characters is used. | |

Converts a binary number to octal. | BIN2OCT(number, [places]) Number is the binary number to be converted. Places is the number of characters to use. If places is omitted, the minimum number of characters is used. | |

Returns a bitwise ‘AND’ of two numbers. | BITAND( number1, number2) | |

Returns a number shifted left by the specified number of bits. | BITLSHIFT(number, shift_amount) | |

Returns a bitwise ‘OR’ of two numbers. | BITOR(number1, number2) | |

Returns a number shifted right by the specified number of bits. | BITRSHIFT(number, shift_amount) | |

Returns a bitwise ‘XOR’ of two numbers. | BITXOR(number1, number2) | |

Converts real and imaginary coefficients into a complex number of the form x + yi or x + yj. | COMPLEX(real_num,i_num,suffix) Real_num is the real coefficient of the complex number. I_num is the imaginary coefficient of the complex number. Suffix is the suffix for the imaginary component of the complex number. If omitted, suffix is assumed to be “i”. | |

Converts a number from one measurement system to another. | CONVERT(number, from_unit, to_unit) Number is the number to be converted. From_unit is a text string, denoting the current unit. From_unit is a text string, denoting the unit to which the number will be cconverted. | |

Converts a decimal number to binary. | DEC2BIN(number, [places]) Number is the decimal number to be converted. Places is the number of characters to use. If places is omitted, the minimum number of characters is used. | |

Converts a decimal number to hexadecimal. | DEC2HEX(number, [places]) Number is the decimal number to be converted. Places is the number of characters to use. If places is omitted, the minimum number of characters is used. | |

Converts a decimal number to octal. | DEC2OCT(number, [places]) Number is the decimal number to be converted. Places is the number of characters to use. If places is omitted, the minimum number of characters is used. | |
