*1 Mixed fraction is supported in the Math input/output mode only.

*2 For information about function input from the MATH function menu, see “Using the MATH Menu” described below.

*3 Tolerance cannot be specified in the Math input/output mode. If you want to specify tolerance, use the Linear input/output mode.

*4 For Σ calculation in the Math input/output mode, the pitch is always 1. If you want to specify a different pitch, use the Linear input/output mode.

*5 This is the number of bytes for a 2 × 2 matrix.
