26.2. Primitive Type

26.2.1. Bool Type

Definition

#undef          bool
#define         bool                boolean

SFMTYPEDEFALIAS(bool, Bool)

#undef          true
#define         true                (TRUE)
#undef          false
#define         false               (FALSE)

Reference: SFMTYPEDEFALIAS

Example

if (SFXAscii::IsDigit(ch) == true) { ... }   // wrong usage
if (SFXAscii::IsDigit(ch)) { ... }           // correct usage

	Note
	The function with return value of the Bool type dose not necessarily return "1" as logical true value. Like C language, the values other than 0 are considered as logical true value in SophiaFramework UNIVERSE.

Bool MyFunction(SIntN flag) {
    return (flag & 0x4000);   // wrong usage
}

	Note
In SophiaFramework UNIVERSE, the Bool type dose not necessarily equal the int type although the logical value is of the int type in C language. If the Bool type is defined as unsigned char type, the return value is always false (=0).

26.2.5. Floating Point Type

Definition

SFMTYPEDEFALIAS(float, Float32)
SFMTYPEDEFALIAS(double, Float64)

	Note
	Since the C/C++ floating point arithmetic operations can be used in SophiaFramework, the BREW helper functions are unnecessary.

	Using the floating point arithmetic operations
	The applet size increases depending on the kinds of floating point arithmetic operations used, since the applet will be linked with the floating point libraries.

Example

Float64 num1(255);
Float64 num2(123.5);
Float64 num3;

num3 = (num1 + num2) / (num1 - num3);

if (num3 < num1) {
      ...
}

Note

	Note
Trigonometric, exponential, and logarithmic functions not included in the BREW API are available in SophiaFramework UNIVERSE. The `SFXTrigonometric` class for fast trigonometric operations can be also used. Reference: Mathematical functions of RealView Compilation Tools for BREW V1.2

26.2.7. Character Type

Definition

SFMTYPEDEFALIAS(char, AChar)
SFMTYPEDEFALIAS(AECHAR, WChar)

	AChar and WChar
AChar is defined as alias of the char type for the single/multi byte character (or the ANSI character). On the other hand, WChar is defined as alias of the AECHAR type (or the uint16 type) for the double byte character. By the way, AECHAR is defined as below in the "AEEStdDef.h" header file of BREW SDK: typedef uint16 AECHAR;
