Description

IEEE754 converter v3

Today, the most prevalent representation of real numbers on computers is IEEE Standard 754 floating point.
This function converts floats to hexadecimal or vice versa using the IEEE-754 standard introduced in SSE instructions set.

Syntax:

IEEE754(a, b)

"a" can be a decimal, hexadecimal or a string.
Hexadecimals are case-sensitive and must be uppercase.
Strings must be used to convert decimals with more than 12 digits.
In CAS mode strings must be used when convert from hexadecimals to floats e.g. IEEE754 ("#123h",16).
In CAS mode when convert from floats to hexadecimals, the result will be a string.

"b" can only be :
0 - Display this help
8, 16, 32 or 64 - bits base conversion
If bases are negative the result will show a string with more digits.

Examples:
IEEE754 (3.14159265359, 64) → #400921FB54442EEAh;
IEEE754 (#400921FB54442EEAh, 64) → 3.14159265359;
IEEE754 ("3.141592653589793", 64) → #400921FB54442D18h;
IEEE754 (#400921FB54442D18h, -64) → "3.14159265358979311599796346854"

In CAS mode:
IEEE754 ("#6Dh",8) → 14.5
IEEE754 (14.5, 8) → "#6Dh"
