X2A
Format
P1
= X2A(P2)
Data Type
U
Function
Converts 16-bit number P2 to a 4-digit hex number in ASCII character form and saves the result
in word array P1. The character of the fourth digit is saved in the first word of P1 and the
characters of the other digits are saved in the following words in sequence.
P1 (I)
The location (or the word array) to save the result.
P2 (I/C)
The number to be converted.
Example 1
$U10
= X2A(
0x34AB
)
/*The 4 words starting from $U10 will be: 51('3'), 52('4'), 65('A'), 66('B') */
W2F
Format
P1
= W2F(P2)
Data Type
U/S
Function
Converts 16-bit number P2 to a floating point number and saves the result in P1.
P1 (I/E)
The location to save the result.
P2 (I/E/C)
The 16-bit number to be converted.
Example 1
$U200
= W2F(
$U10
) (S)
D2F
Format
P1
= D2F(P2)
Data Type
UD/SD
Function
Converts 32-bit number P2 to a floating point number and saves the result in P1.
P1 (I/E)
The location to save the result.
P2 (I/E/C)
The 32-bit number to be converted.
Example 1
$U200
= D2F(
$U10
) (SD)
F2W
Format
P1
= F2W(P2)
Data Type
F
Function
Converts floating point number P2 to a 16-bit number and saves the result in P1.
P1 (I/E)
The location to save the result.
P2 (I/E/C)
The floating point number to be converted.
Example 1
$U200
= F2W(
$U10
) (F)
F2D
Format
P1
= F2D(P2)
Data Type
F
Function
Converts floating point number P2 to a 32-bit number and saves the result in P1.
P1 (I/E)
The location to save the result.
P2 (I/E/C)
The floating point number to be converted.
Example 1
$U200
= F2D(
$U10
) (F)
