HP 46 User Manual

To ensure greater accuracy, the HP-46 internally performs all calcula-
tions using a ten-digit number and a power of ten (whether or not all
the digits are visible in your printing format). Expressing values as
numbers multiplied by powers of 10 is called ‘scientific notation’ (i.e.,
23712.45 = 2.371245 x 10* in scientific notation).
Scientific notation can be specified as a format and is helpful when you
are working with very large or small numbers. Press 8 (71 and
follow it with a numerical key between 0 and 9. For example, =mm SCI
5 specifies scientific notation with the number rounded to show 5
places after the decimal point. In this format, 2.371245 x 10* would
look like this:
2¢37125 +0,4 °
Exponent of 10
If a number is too large for the printing format specified, the calculator
automatically prints the number in scientific notation. For example, if
you have pressed FIX 8, and key in the number 100, the calculator will
print the number in scientific notation because there is not enough
room to print three places before the decimal point:
Press: =3 8 100 1000000600+02 ¢

Numbers that are too small to be seen in the specified FIX format are
printed as zero. For example, print the number .000396 in FIX 3
format and ®mm SCI| 3 format:
Press : Cm) 3 .000396 | 0,000 o
