Inputting and Editing Calculations
*
1
Mixed fraction is supported in the Math input
mode only.
*
2
For information about function input from the
MATH function menu, see “Using the MATH
Menu” on page 1-3-12.
*
3
Tolerance cannot be specifi ed in the Math input
mode. If you want to specify tolerance, use the
Linear input mode.
*
4
For
Σ calculation in the Math input mode,
the pitch is always 1. If you want to specify a
different pitch, use the Linear input mode.
*
5
This is the number of bytes for a 2
× 2 matrix.
