To change the sign of a number that was entered previously, just press _. (If the number has an exponent, _affects only the mantissa — the non–exponent part of the number.)

Exponent of TenExponents in the Display

Numbers with exponents of ten (such as 4.2 ⋅ 10–5are displayed with an  preceding the exponent (such as ).).

A number whose magnitude is too large or too small for the display format will automatically be displayed in exponential form.

For example, in FIX 4 format for four decimal places, observe the effect of the following keystrokes:

Keying in Exponents of Ten

Use ` (exponent) to key in numbers multiplied by powers of ten. For example, take Planck's constant, 6.6262 ⋅ 10–34:

1.Key in the mantissa (the non–exponent part) of the number. If the mantissa is negative, press _after keying in its digits.
