Where 754 fits
Why 754 is special
It is why 0.1 plus 0.2 does not equal 0.3 in most programming languages: a tenth has no exact representation in binary, exactly as a third has none in decimal.

DCCLIV uses the subtractive pair IV: one before five — five minus one.

1 × 512 + 0 × 256 + 1 × 128 + 1 × 64 + 1 × 32 + 1 × 16 + 0 × 8 + 0 × 4 + 1 × 2 + 0 × 1 = 754

1 × 512 + 3 × 64 + 6 × 8 + 2 × 1 = 754
Hexadecimal
2 f 2
2 × 256 + f × 16 + 2 × 1 = 754
Read as powers of two: 512 + 128 + 64 + 32 + 16 + 2 = 754.
In historical numeral systems
Egyptian
7 coils of rope, 5 hobbles, 4 strokes
7 × 100 + 5 × 10 + 4 × 1 = 754. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 2 vertical wedges (sixties place), 3 corner wedges + 4 vertical wedges (units place)
12 × 60 + 34 = 754. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then nu, then delta, marked as a numeral
psi-nu-delta + keraia
psi + nu + delta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then shin, then nun, then dalet
tav-shin-nun-dalet
tav (400) + shin (300) + nun (50) + dalet (4) = 754, written in descending order.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
IEEE 754 labels binary floating-point arithmetic and is cited by number in language specifications worldwide.
IEC 60559 is technically identical to IEEE 754 and exists so other standards can cite floating point through an ISO route.

Technology & computing
IEEE 754 specifies binary floating-point formats, rounding rules, and special values including signed zeros, infinities and NaN. Values such as 0.1 are not exactly representable, so arithmetic on them accumulates small errors.

Common questions
Is 754 a prime number?
No, 754 is not prime.
What are the factors of 754?
The factors of 754 are 1, 2, 13, 26, 29, 58, 377, 754.
What is 754 in Roman numerals?
754 in Roman numerals is DCCLIV. IV is subtractive: one before five — five minus one. Written additively it would be DCCLIIII, which Roman inscriptions used freely — the strict subtractive form is a later convention.
