Calculates the principal value of the inverse cosine of a number.

Calculates the principal value of the inverse sine of a number.

Calculates the principal value of the inverse tangent of a number.

Calculates the angle between the x-axis and a line drawn from the origin to a point represented by its (x,y) co-ordinates.

The co-ordinates are passed as arguments to the function. This function returns the same result as arctan(y/x), but:

1. it adds +/-pi to the result, if x is negative

2. it sets the result to +/-pi/2, if x is zero but y is non-zero.

Calculates the cosine of a number.

Divides aDividend by aDivisor.

The quotient is returned, and the remainder is stored in aRemainder. The remainder has same sign as the dividend.

Calculates the value of e to the power of x.

Generates a stream of uniformly distributed pseudo-random real numbers in the range, 0 to 1.

Calculates the fractional part of a number.

The fractional part is that after a decimal point. Truncation is toward zero, so that Frac(2.4)=0.4, Frac(2)=0, Frac(-1)=0, Frac(-1.4)=0.4.

Calculates the integer part of a number.

The integer part is that before a decimal point. Truncation is toward zero, so that int(2.4)=2, int(2)=2, int(-1)=-1, int(-1.4)=-1, int(-1.999)=-1.

Calculates the integer part of a number.

The integer part is that before a decimal point. Truncation is toward zero, so that int(2.4)=2, int(2)=2, int(-1)=-1, int(-1.4)=-1, int(-1.999)=-1.

This function is suitable when the result is known to be small enough for a 16-bit signed integer.

Calculates the integer part of a number.

The integer part is that before a decimal point. Truncation is toward zero, so that int(2.4)=2, int(2)=2, int(-1)=-1, int(-1.4)=-1, int(-1.999)=-1.

This function is suitable when the result is known to be small enough for a 32-bit signed integer.

Determines whether a value is finite.

In this context, a value is finite if it is a valid number and is not infinite.

Determines whether a value is infinite.

Determines whether a value is not a number.

Determines whether a value is zero.

Calculates the natural logarithm of a number.

Calculates the logarithm to base 10 of a number.

Calculates the modulo remainder.

This is the value of p mod q, the modulo remainder when dividing p by q. The result is given by p - q int (p/q): it has the same sign as p: thus, 5 mod 3 = 2, -5 mod 3 = -2. No error is raised if non-integer arguments are passed.

Multiply aX by aY to generate a 128 bit result.

The high order 64 bits of this calculation are stored in aOutH, and the low order 64 bits are stored in aOutL.

Evaluates the polynomial: {a[n]X^n + a[n-1]X^(n-1) + ... + a[2]X^2 + a[1]X^1 + a[0]}.

Evaluates the polynomial: {a[n]X^n + a[n-1]X^(n-1) + ... + a[2]X^2 + a[1]X^1 + a[0]}.

Calculates the value of x raised to the power of y.

The behaviour conforms to that specified for pow() in the ISO C Standard ISO/IEC 9899 (Annex F), although floating-point exceptions are not supported.

Calculates the value of 10 to the power of x.

Generates a stream of uniformly distributed pseudo-random integers in the range, 0 to KMaxTInt.

For each stream of pseudo-random numbers you wish to generate, you should pass the reference to the same 64-bit seed on each call to this function. You should not change the seed between calls.

Gets 32 random bits from the kernel's random number generator.

The returned random data may or may not be cryptographically secure but should be of a high quality for non-cryptographic purposes.

This function uses a cryptographically strong random number generator to generate the random data, which can be slower than insecure generators. If security is not important, a faster generator may be used such as Math::Rand() .

Fills the provided descriptor with random data up to its current length. The number of random bytes required should be specified by setting the length of the descriptor that is passed to this function.

The returned random data may or may not be cryptographically secure but should be of a high quality for non-cryptographic purposes.

Fills the provided descriptor with random data up to its current length. The number of random bytes required should be specified by setting the length of the descriptor that is passed to the function.

If the returned random data cannot be guaranteed to be cryptographically secure, the function will leave with KErrNotReady to indicate that the returned data should not be used for cryptographic purposes.

The security strength of the cryptographically strong random number generator is 256 bits.

Gets 32 random bits from the kernel's random number generator.

If the returned random data could not be guaranteed to be cryptographically secure, the function will instead leave with KErrNotReady to indicate that data was not available.

The security strength of the cryptographically strong random number generator is 256 bits.

Rounds to a specified number of decimal places.

The function rounds a number to a given number, n, of decimal places. Rounding may be thought of as multiplying the number by 10 to the power of n, rounding to the nearest integer, and then dividing the result by 10 to the power of n and returning that as the answer.

In the process of rounding, numbers ending with .5 are rounded away from zero, so that 1.5 becomes 2, 2.5 becomes 3, -1.5 becomes -2, etc.

Calculates the sine of a number.

Calculates the square root of a number.

Calculates the tangent of a number.

Divides aDividend by aDivisor.
