|
|
•tan |
Tangent of an angle
|
|
•atan |

|
Exponential and logarithmic functions:
|
•exp |

|
|
•modf |
Breaks a number into an integral and a fractional part.
|
|
•sqrt |
Square root
|
Rounding functions
|
•ceil |
Round to smallest integral value that is larger than the value
|
|
•floor |
Round to largest integral value that is smaller than the value
|
Other functions
|
•fabs |
Absolute value of float
|
|
•fmin |
Returns the smallest of two values
|
|
•fmax |
Returns the largest of two values
|
|
•IsInf |
Checks if an value is infinite
|
|
•IsNaN |
Checks if an value is not a number
|
Conversion functions
|
•floatToStr |
Converts a float to a string
|
|
•strToFloat |
Converts a string to a float
|
|
•doubleToStr |
Converts a double to a string
|
|
•strToDouble |
Converts a string to a double
|
|
•degToRad |
Converts an angle from degrees to radians
|
|
•radToDeg |
Converts an angle from radians to degrees
|
|
•degToPosition |
Converts an coordinate from decimal degrees to RTCU GPS position
|
|
•positionToDeg |
Converts an coordinate from RTCU GPS position to decimal degrees
|
Besides the situations where the functions are described to return Infinity values or NaN, ordinary operations can also cause these error values, if the numbers either becomes too large, or perform illegal operations, such as division with zero, which can be checked with the isInf and isNaN functions.
Please note that when using the Floating-Point Math functions in X32 and NX32 compilation mode then math.inc must be explicitly included by the application.
When using the NX32L compilation mode, math.inc is included by default.
DOUBLE and FLOAT support:
The math library is implemented with support for dual precision depending on whether the Double math library option in the project settings is checked.
When this option is unchecked (default) then all functions in this library will automatically change to operating with FLOAT instead of the documented DOUBLE.
