4 (convert) 2  key expression_unit1 4 _unit2 ⇒ expression_unit2 Converts an expression from one unit to another. The units must be in the same category. The _ underscore character designates the units. For a list of valid pre-defined units, refer to the module about constants and measurement units. You can press 2 9 to select units from a menu, or you can type the unit names directly. To get the _ underscore when typing units directly, press ¥  3_m 4 _ft ¸ Note: The 4 conversion operator does not handle temperature units. Use tmpCnv() and @tmpCnv() instead. 9.842...ø_ft 10^() CATALOG 10^ (expression1) ⇒ expression 10^ (list1) ⇒ list Returns 10 raised to the power of the argument. For a list, returns 10 raised to the power of the elements in list1. 10^(1.5) ¸ 10^{0,ë 2,2,a} ¸ 31.622... {1 1 100 100 10a} 10^(squareMatrix1) ⇒ squareMatrix 10^([1,5,3;4,2,1;6,L2,1]) ¸ Returns 10 raised to the power of squareMatrix1. This is not the same as calculating 10 raised to the power of each element. For information about the calculation method, refer to cos(). 19..194536......EE76 7.652...E6 8.171...E6 7.115...E6 5.469...E6 65..687153......EE66 4.468...E6 squareMatrix1 must be diagonalizable. The result always contains floating-point numbers. xê CATALOG (^-1) expression1 xê ⇒ expression list1 xê ⇒ list Returns the reciprocal of the argument. For a list, returns the reciprocals of the elements in list1. 3.1^ë 1 ¸ .322581 {a,4,ë.1,xì 2}^ë 1 ¸ {1a 1 4 ë 10. 1 xì 2} squareMatrix1 xê ⇒ squareMatrix Returns the inverse of squareMatrix1. [1,2;3,4]^ë 1 ¸ [1,2;a,4]^ë 1 ¸ squareMatrix1 must be a non-singular square matrix. Appendix A: Functions and Instructions 911
